YALOK Anti Theft License Plate Screws Kits- Rustproof Stainless Steel Car Tag Plate Mounting Hardware, M6 (1/4") Tamper Proof Fastener Nut, Caps Cover for Front Rear Frame Holder Mounting（at-Black/4）

No pude usar los tornillos, son demasiado largos y solo trae de una longitud. Solo use los tapones negros.

Expected better, but these screws have issues which make them easy to defeat. Just a small flat head screwdriver is able to unscrew these as the security pin in the middle of the screws are too shallow and are not high enough to prevent sticking something in to try turn the screw.. using some house keys, I'm able to get enough grip to turn the screw. I'm still going to try use these screws as a visual deterrent and they fit, but might not stop someone from trying their luck with standard tools.

Worked as advertized. Easy to install.

These were purchased for 3 different vehicles. One used the screw type to install while the other two used the bolt type. The two vehicles that used the bolt had the current license plate put on with the screw type and the screws stuck out; because the wrong type had been put on the vehicles (go figure). Since the packs that were ordered has both types it was easy to use the type that was actually the correct one. In both cases the screws and bolts installed easily. The sliver caps make for a nice finish touch to the overall look and makes it harder for anyone to know without removing the cap what kind of screws/bolts were used to attached the plate. Nothing will stop a determined thief; but these are a good deterrent and for the price if it stops someone from stealing your plate it is well worth it.

Very good quality but I didn't check its length carefully, they are too long to be used. I can use them for other purposes so I am not returning them.
