"Nailock" is a reliable locking fastener made possible by a special technology that permanently adheres a special nylon to the screw section. When the screw processed with Nailock is tightened, a strong frictional bonding force is generated throughout the screw section, providing a permanent locking function against vibrations and impacts. Additionally, even with repeated use, the locking effectiveness is outstanding. It does not damage the mating screw, and there is no concern about rust or peeling of plating, contributing to the lightweight and improved weather resistance of the product. 【Features】 ■ Strong locking function ■ Reusable ■ Does not loosen ■ Rust-resistant ■ Excellent workability *For more details, please refer to the catalog or feel free to contact us.
