RS PRO M12, Zinc-Plated Steel Nylon Insert Lock Nut


These RS PRO lock nuts will keep your bolts tightly in place, even in situations where they're under severe strain. They're made of zinc-plated steel that's resistant to rust, acid and oil corrosion, making them a long-lasting choice for use in demanding environments.

The lock nuts are designed to be resistant to vibrations and torque, and their nylon inserts increase the grip between the nut and bolt to ensure the connection stays strong. This saves you time and effort, as you won't need to manually retighten the lock nut.

When you screw the mating bolt into the nut, the bolt compresses the nylon, leaving no space for liquids like oil or water to leak into your devices. That means it will keep your components dry and free from rust or water damage.
