Tired of license plate theft or unauthorized removal? Our Anti-Theft License Plate Screws are designed to provide maximum security while ensuring durability against rust and corrosion. Made from high-grade stainless steel (304/316), these M6 (1/4") tamper-proof screws are the ultimate solution for securely mounting front and rear license plates on cars, trucks, motorcycles, and trailers.
✔ Anti-Theft & Tamper-Proof Design – Unique drive style (security hex, torx, or custom pattern) prevents easy removal without the matching tool.
✔ Rustproof Stainless Steel – Made from 304/316 stainless steel, resistant to corrosion, salt spray, and harsh weather conditions.
✔ Universal M6 (1/4") Size – Fits most standard license plate mounts, frames, and holders worldwide.
✔ Easy Installation – Includes matching security bits for hassle-free mounting.
✔ Durable & Long-Lasting – Will not strip, break, or corrode like cheap aluminum or zinc-plated screws.
✔ Legal Compliance – Helps prevent license plate theft, which is required in many states/countries.
