What Are The Plastic Screws In Car Bumpers Called? Explained
They’re usually called bumper clips, push pins, retainer clips, or plastic rivets; if the fastener has a center pin, it’s a push-type retainer, and if it threads in, it’s a plastic screw or trim screw. Mix up the name or pry them out the wrong way, and you crack the bumper cover, strip the hole, or lose hardware that holds the liner in place. Here’s how to identify the parts, remove them safely, replace them correctly, and order the right match.

Bumper plastic fasteners are often not screws at all. Most are bumper retainer clips, push pins, push-type retainers, or plastic rivets that hold the bumper cover, splash shield, or wheel-liner edge in place. True screw-style pieces do exist, but many fasteners only look threaded from the top.
The difference matters because the removal method changes. A push pin usually has a center plunger that releases the legs. A trim screw generally turns out. A retainer clip may pop free with a trim tool. Twist the wrong type, and the head rounds off or the hole tears.
Why some look like screws but are not threaded
Many bumper fasteners have a slotted or cross-shaped head so they resemble a screw. The body underneath may be smooth, barbed, or expansion-style instead of threaded. That design lets the fastener lock into plastic without cutting new threads every time.
That is why a quick visual check is not enough. Look underneath the head, not just at the top. If the center pin moves inward, it is likely a push-type retainer. If the body expands when driven in, it is a plastic rivet style. If it truly turns in and out, it is the screw-style version.
Bumper cover and bumper beam are different parts
The bumper cover is the outer plastic or composite shell you see. The bumper beam is the structural piece behind it. Fasteners hold the cover to brackets, liners, and adjacent trim, but beam damage changes the repair decision.
That difference matters during assessment. A cracked cover with sound structure may be repairable, while beam damage can shift the job toward replacement. Do not order fasteners for the cover until you know the cover tabs, mounting points, and underlying support are intact enough to reuse.
Bumper fastener guide
| Common name | What it looks like | Where it is used on the bumper | Reusable? | What to ask for at a parts counter |
|---|---|---|---|---|
| Push pin | Head with a center pin that presses inward | Top edge, liner edge, splash shield tabs | Sometimes, if the legs and head are undamaged | Push-type bumper retainer clip |
| Retainer clip | Barbed plastic clip with locking legs | Corner mounts, undertray edges, side retainers | Sometimes, if it still grips tightly | Bumper cover retainer clip for your trim level |
| Plastic rivet | One-piece plastic fastener that locks after insertion | Wheel liner, lower shield, some fascia mounts | Usually no after removal | Plastic rivet for bumper cover or liner |
| Trim screw | Plastic or metal-thread style head that turns out | Upper cover edge, brackets, grille supports | Sometimes, if threads are intact | Trim screw for bumper fascia |
| Speed clip | Spring steel clip behind a screw hole | Behind brackets or thin tabs that need a threaded bite | Often yes, if not bent or rusted | Bumper speed clip or captive nut clip |
How do you remove bumper clips without damage?
Use the correct tool, start at the release point, and keep force straight, not sideways. Most bumper clips come out cleanly if you release the lock before pulling. If the fastener resists, stop and identify the style again. A broken clip can tear the cover hole and turn a simple removal into repair work.
Tools that fit the job
A nylon trim tool, small pick, flat screwdriver with a taped edge, and needle-nose pliers cover most bumper fasteners. Use the least aggressive tool that will release the lock. Metal tools can work, but they are easier to slip with and scar painted surfaces.
For a push pin, depress or lift the center pin first. For a trim screw, back it out straight. For a clip with legs, pry under the head evenly so the legs collapse instead of snapping. If access is tight, remove liner sections first rather than dragging the fastener out at an angle.
Plastic screws checklist
- Clean dirt from the fastener head and surrounding edge.
- Identify the type before touching it.
- Support the bumper cover near the clip so the panel does not flex.
- Release the center pin or threaded section first.
- Pull straight out after the lock is free.
- Inspect the hole, tab, and head for cracks or stretch marks.
- Set aside any fastener that feels loose, bent, or warped.
Signs a clip should be replaced
A clip should be replaced if the head is mushroomed, the legs stay spread open, the locking tabs are cracked, or the hole in the cover is elongated. If it no longer grips firmly, reuse only invites rattles and panel misalignment.
Picture a lower bumper corner with two missing fasteners after a parking scrape. If the remaining clip sits crooked or falls out with light finger pressure, it is not reusable. Order a new one before reinstalling the cover, or the edge will never sit flush.
Are bumper clips reusable?
Some bumper clips are reusable, but not all. A clean push pin or retainer can go back in if the legs, head, and receiving hole still hold shape. Plastic rivets and damaged retainers are often one-time-use once removed or stressed. The safe rule is simple: reuse only if the clip still locks like new.
When a clip can go back
A clip can usually be reused when it slides in firmly, the center pin resets normally, and the head sits flat without wobble. The hole in the cover should not be ovaled out, cracked, or widened. If the fit feels loose during removal, it will likely stay loose after reinstallation.
When the retainer is one-time-use
One-time-use fasteners include many plastic rivets, expanded push pins that split during removal, and clips damaged by impact. If the bumper cover was hit hard enough to deform the mounting zone, assume the original fastener may no longer hold correctly.
A common first-timer mistake is reinstalling a deformed clip because it “still fits.” It may fit for a moment, then pop loose when the cover flexes over a driveway dip or a curb touch. That is when liner edges start hanging down.
How to judge broken tabs and stretched heads
Check the clip body, not just the head. Cracked barbs, missing legs, stretched heads, and bent center pins are all signs to replace it. Also inspect the bumper cover tab around the hole. If the tab is torn, a new clip may not hold without plastic repair.
How do you order the right replacements?
Ask for the exact bumper retainer clip or fastener used at that location, not a generic “plastic screw.” Vehicle-specific fitment matters because head diameter, stem length, leg shape, and hole size vary by model year, trim, and bumper position. A clip that fits the upper cover may not fit the liner or lower shield.
What to say at the parts counter
Start with the vehicle year, make, model, trim, and the exact location on the bumper. Say whether you need an upper bumper cover retainer, lower splash shield fastener, wheel-liner clip, or grille/side retainer. If possible, bring the old clip, even if broken.
Ask for the clip by function and position, not only by color. Black, white, and gray clips can look similar but differ in stem length or head size. If the counter staff can match the shape, diameter, and length from the sample, you are more likely to leave with the correct part.
Why trim and bumper position matter
Fastener choice often changes with trim level, sensor package, fog light layout, or air deflector design. Front and rear bumpers may use different retainers. Left and right side positions can also differ, especially near wheel liners or corner brackets.
Say your compact SUV has a parking sensor in the rear bumper and a plain front fascia. The rear may use extra clips around the sensor bracket or camera trim. Ordering a front fastener for the rear corner may leave you with a part that locks in the wrong way or does not align with the opening.
Do bumper fasteners affect sensors and cameras?
Yes. Every bumper repair starts with a sensor audit, and the inspection should include structural damage, paint condition, and sensor or camera placement. A fastener that sits in the wrong hole can shift the cover, pinch wiring, or change how a sensor bracket sits behind the fascia. Backup camera mounts must also stay aligned and undamaged.
Parking sensor checks before removal
Before you remove the bumper cover, confirm where the parking sensors sit and how they are mounted. Some are clipped to the cover, others sit in brackets attached behind it. Mark their positions and protect the harness. If a clip is broken near a sensor opening, the cover may need repair before it goes back on.
Backup camera mounting points
A backup camera can sit in or near the bumper area, often in the center of the rear cover, trim bezel, or tailgate adjacent to the bumper line. Do not pry blindly near that area. If the mount shifts, the camera angle can change and the image can point too high, too low, or off-center.
When recalibration may be needed
Sensor-equipped bumpers sometimes need recalibration after reinstallation, especially if the cover position changes or brackets were removed. Keep the fastener locations exact and recheck panel gaps before final tightening. If the cover sits proud on one side, the sensor array may not point the same way as before.
Bumper repair or replacement?
Repair is preferred when the bumper cover’s structural integrity is maintained. Replacement is recommended when the cover cannot hold its shape. Bumper repair can restore dents, scuffs, paint transfer, and cracks on plastic and composite covers, but the bumper beam, mounting tabs, and sensor zones must still support a proper fit.
When plastic welding can work
Plastic welding is used to rejoin cracked sections when the damage is contained and the structure is sound. Minor depressions may be repaired with body filler after the plastic is stabilized. The goal is to return the cover to a shape that will hold clips, align with adjacent panels, and accept finish work.
When heat reshaping can restore fit
Heat reshaping is used to return deformed plastic to its original profile. It is useful when the cover is warped but not split through a critical mount. The repair should be done before primer and paint, because the panel must hold its shape first and the finish second.
How paint code and blending affect the finish
If the cover needs refinishing, the factory paint code is the starting point for color match. Blending into surrounding panels helps the repair blend visually with the rest of the body. Paint issues are part of the repair decision, because a cover with good structure may still need refinishing after plastic work.
The shop’s listed turnaround is 1–2 days for repair, with a cost range of $150–$600. Replacement is listed at $600–$1,500. The shop says 60–70% of bumper damage is repairable rather than replaced, but that only applies when the cover still holds its shape and the beam and mounting points do not force a full replacement.
Frequently asked questions
What are the plastic screws in car bumpers called?
They are usually called bumper clips, push pins, retainer clips, or plastic rivets. If the fastener has a center pin, it is a push-type retainer. If it actually threads in and out, it may be a plastic screw or trim screw. The name depends on the style.
Are bumper clips and bumper screws the same thing?
No. People often use the terms interchangeably, but they are not the same fastener. A bumper screw turns out. A bumper clip or retainer usually locks into place with a pin, barb, or expanding leg. Matching the removal method to the fastener style avoids broken tabs.
What tool do I need to remove bumper clips?
A nylon trim tool is the safest first choice, followed by a small pick or taped flat screwdriver for tight spots. Some clips release with finger pressure once the center pin is lifted. Use the lightest tool that can release the lock without scratching paint or cracking the cover.
How do I know if a bumper fastener is broken or reusable?
Inspect the head, legs, and locking shape. A reusable fastener still grips firmly, sits flat, and keeps its original shape. Replace it if the head is stretched, the barbs are cracked, or the hole is ovaled out. Loose fit means trouble later.
Are plastic bumper retainers vehicle-specific?
Yes. Many are specific to the year, make, model, trim, and bumper position. Upper cover clips, lower shield fasteners, and wheel-liner retainers can all differ on the same vehicle. Bring the old fastener to the parts counter if you want the closest match.
Do bumper fasteners affect sensors or camera alignment?
They can. A missing or wrong fastener can shift the bumper cover, which changes how sensors and camera mounts sit behind it. That is why every repair should start with a sensor audit and end with a check of panel alignment, mounting points, and any recalibration needed.
