RS PRO, Bright Zinc Plated Steel Lock Nut, DIN 985, M5

These RS PRO lock nuts are designed to give your bolts a greater resistance to vibrations and torque, keeping them tightly in place even if any severe movement might occur. Their nylon inserts increase the grip between the nut and bolt to make sure the connection stays strong and does not need manual retightening.
When you screw the mating bolt into the nut, the bolt compresses the nylon, leaving no room for liquids like water and oil to seep through into devices. This helps keep components dry and free of water damage or rust.
The lock nuts are made of zinc-plated steel that's resistant to corrosion from acids and oils. This zinc coating helps ward off rust as well so your bolts will be securely fastened for an extended period of time.
