RS PRO Stainless Steel Plain Locknut DIN 985 M6 10mm Width 6mm Height 521-945

RS PRO 521-945 is a stainless steel plain locknut with a nylon insert, designed to meet DIN 985 standards. Manufactured from A2 grade stainless steel, this locknut offers excellent durability and resistance to corrosion, making it suitable for harsh industrial environments and prolonged use.

The locknut incorporates a glass-filled nylon insert which enhances its locking capability by deforming onto the screw thread providing a secure grip that resists loosening from vibrations or dynamic loads. The plain finish gives it a clean, functional look while offering environmental resistance.

This M6 size Locknut features a 10mm width and a 6mm overall height, making it compatible with a variety of fastening applications. It is particularly effective where fastening safety is critical such as automotive assembly, industrial machinery, and domestic appliances like washers and dryers.

Unlike conventional nuts, the nylon insert eliminates the need for additional lock adhesives and is ideal for use with soft materials such as plastics and wood where high surface pressure could cause damage. For best results, it is recommended to finger tighten and then tighten to the specified torque using suitable tools.

The nylon insert's locking function degrades with reuse due to deformation, so repeated use is discouraged to maintain fastening integrity. Country of Origin: China. Constructed from A2 stainless steel. Complies with DIN 985 standard.
