Self-locking nut with nylon insert M12 DIN 985 strength class 4.8 zinc (pack 60pcs) STROYMETIZ UTORM3040078

Hexagon self-locking nut DIN 985 has a hexagonal shape for easy wrench gripping during installation from any convenient side. It is manufactured with a through-threaded hole in the center for easy screwing onto a bolt, screw, or stud. Equipped with a special nylon insert that provides tightness to the connections. The nylon insert prevents the nut from moving along the thread and prevents spontaneous unscrewing of the threaded assembly, contributing to its long service life. Advantages: • tightness of the connection; • absence of free play of the fastener along the thread; • corrosion resistance; • long service life; • installation without the use of special equipment; • quick disassembly if necessary; • no degradation under temperature fluctuations or UV exposure. Locking self-locking nuts are used in instrumentation and machine building to solve industrial and household tasks. They are installed when securing plumbing fixtures, various equipment, and units.
