How to Deal with Oversized License Plate Mounting Holes?
4 Answers
Solutions for oversized license plate mounting holes are as follows: Using self-tapping screws for installation: Simple and convenient installation, only requiring a screwdriver for smooth installation. Slightly less secure, as screws or license plates may be lost when driving through waterlogged sections. Using riveting for installation: At the vehicle management office, the license plate can be riveted onto the bumper. Secure installation, but tools are hard to find. If the bumper is damaged, it will need to be re-riveted or installed using other methods. Using self-tapping screws with anti-theft bolts for installation: Secure installation, rust-proof, and offers some anti-theft capability. Anti-theft bolts need to be sourced independently, especially stainless steel anti-theft bolts, nuts, washers, and spring washers, all of which must be made of stainless steel.
The oversized license plate mounting holes can be really annoying. The plate wobbles when installed and rattles when driving, making it prone to loosening and falling off. From my experience, the first solution is to add washers: find some metal or rubber washers, place them on the mounting screws to fill the gaps, preferably slightly smaller than the hole size, so the plate stays firmly in place when the screws are tightened. If the holes are excessively large, try using screws with larger heads or a license plate frame to encase the entire plate for added stability. During daily use, occasional checks on screw tightness are crucial—I personally take a quick look every month just in case. Don’t forget to regularly clean debris from the holes, as dust buildup can worsen the issue. When handled properly, this not only avoids the embarrassment and fines of losing a plate on the road but also ensures much safer driving.
I've encountered the issue of oversized license plate holes several times while working on cars. The license plate frames just wouldn't stay secure. Here's a simple DIY solution: Head to an auto parts store and grab a pack of thick washers (plastic or silicone ones work best) for just a few bucks. Slide them onto the screws to fill the gap in the holes - problem solved instantly. I always keep various sizes of spare parts in my drawer, saving both time and money on mechanic visits. Remember to clean out any rust or debris from the holes before installation, otherwise the washers might be hard to fit in. Another handy tip: use double-sided tape to temporarily secure the plate before screwing it in, preventing any movement during installation. Over long-term use, vibrations can slightly loosen the screws, so I recommend checking them quarterly - safety should never be overlooked.
A loose license plate hole is no good—it makes the plate wobble and unstable, which can be dangerous at high speeds. My solution is simple: buy a rubber washer or cut a small piece from an old tire, stuff it into the hole, and then secure the plate with screws. A regular wrench will do the job—beginners shouldn’t worry. Just measure the hole size, match the washer, and you’re done in five minutes. Also, make sure the plate isn’t sticking out too much at the edges to avoid wind resistance worsening the looseness. Fix it promptly to avoid traffic fines or unsafe driving.
