Best Anti-Theft Screws for Number Plates in 2027

This kit targets plate theft directly. Each screw has a hex button head with a thimble in the center. An ordinary Allen key cannot install or remove it. You need the M6 anti-theft screwdriver that comes in the box. That is the core of what a thief-proof plate needs, and it ranks first on our spec score here.

Rust is the second worry on a bumper or trunk. The screws are 304 stainless steel, and the maker lists them as rust and corrosion resistant. The finish is black, with black caps over the heads. The screws are M6 (1/4 in) thread and 20 mm long, and the kit lists self-tapping and machine types. That covers both mounting styles.

The kit has eight screws, four nuts, caps and eight foam pads to cut rattle. It also lists a 1 yr warranty. Among the five reviewed here, it is the only one that lists a warranty.

LivTee ranks second. It uses the same basic idea as the leader: a special M6 anti-theft screwdriver with a plum-shaped tip, not an ordinary hex wrench. A thief with a standard set cannot simply back the screws out. Four screws is tied for the lowest count on this page. Check how many mounting holes your plates use before you buy.

The screws are 304 stainless steel, M6 (1/4 in) thread, 20 mm long. Rust and corrosion resistance is listed. That matters because plate screws sit in rain and road spray all year. The listing also describes a black zinc plated finish. The maker does not publish whether they are self-tapping or machine screws, so check your plate holes first.

In the box are four screws, four foam pads, four washers, four screw covers and four nylon inserts. The nylon inserts and foam pads help with fit and rattle. That covers fitting and noise control in one pack. The maker does not list a warranty term.

YALOK ranks third. Its security screws use a pan head with a hexagonal button top and a thimble in the center. An Allen wrench cannot install or remove them. Only the supplied anti-theft screwdriver works. For a buyer who worries about plate theft, that is the feature that counts, and the kit delivers it. Keep that driver in a safe place at home, since you need it to remove the screws later.

The material is 304 stainless steel, with rust and corrosion resistance listed. Thread is M6 (1/4 in) and length is 20 mm. The finish is black. The kit lists self-tapping screws only, with no machine type. The listing says they suit holes that use nylon or plastic retainers.

The kit includes eight screws, nuts, caps, a screwdriver and rattle pads with adhesive backing. The listing mentions nylon plug-ins that adjust the size of pre-drilled bumper holes. The pads also help keep the plate from scratching paint, per the listing. It carries no listed warranty.

FEAOXYO ranks fourth. The listing says the hexagonal design cannot be installed or removed with a standard Allen wrench. The included anti-theft screwdriver is the only tool that fits. That is the right basic protection against plate thieves. The weak spot is the data: the maker does not publish how many screws come in the kit.

The screws are 304 stainless steel with an oxidation blackening process. Rust and corrosion resistance is listed, and the maker says the finish will not fade. Thread is M6 (1/4 in) and length is 20 mm. Both self-tapping and machine types are listed, so one kit can suit different mounting holes.

Extras include caps, nuts, washers and foam anti-rattle pads. The pads sit behind the plate to cut vibration noise and keep metal from rubbing the paint. The warranty is not listed. Since the count is missing, check the listing before you buy to see how many screws you get.

Ranked fifth, BGGTMO puts looks forward as much as security. The screws are black, finished with an electrophoretic blackening process that the maker says will not fade. Matte black caps cover the heads. Under the caps, the pan heads have a hex button top with a thimble in the center, so an Allen wrench will not work.

The material is 304 stainless steel, marked rust and corrosion resistant. Thread is M6 (1/4 in) and length is 20 mm. The maker lists self-tapping screws and nylon inserts, which suit front bumpers or trunks with pre-drilled holes. Machine bolts are not listed in the specs, so this kit is for self-tapping mounting.

You get eight screws, a screwdriver, nuts, washers and eight rattle pads. The adhesive pads go on the back of the plate to cut vibration noise and avoid paint scratches. Warranty length is missing from the specs. Its size matches the kits above it, so choose on mounting style and looks.
