Product Description

RS PRO 521-939 Stainless Steel Locknut M5 Nylon Insert with Plain Finish complies with DIN 985 and is engineered for secure fastening in challenging conditions.

This locknut features a nylon insert that deforms to the fastener's thread, preventing loosening without adhesives. The use of A2 stainless steel ensures durability and resistance to environmental factors, suitable even for food industry applications. The plain finish adds additional corrosion protection.

Locknuts are essential in applications with high vibration or dynamic loading, providing reliable fastening where conventional nuts might fail. This M5 size locknut has an 8 mm width across flats and a 5 mm overall height, providing a compact yet robust solution.

Common industrial uses include automotive manufacturing, industrial machinery assembly, and domestic appliance production such as washers and dryers. The product is especially recommended where fastening security is critical and soft materials are involved.

The nylon insert allows the locknut to maintain clamp load over time, though reuse is discouraged as the insert's effectiveness diminishes after removal. Made from A2 grade stainless steel for corrosion resistance. Glass-filled nylon insert maintains secure fastening under vibration.

Compact M5 size fits standard metric fasteners. Compliant with DIN 985 standard for locking nuts. Suitable for industrial, automotive, and domestic appliance use. Manufactured in China with stringent quality controls.
