Value Collection 41751 M5 Hex Lock Nut Nylon Insert Din 985

Product Description

The VALUE COLLECTION 41751 is a metric hex lock nut with a nylon insert locking mechanism, manufactured from Class 8 steel with a zinc-plated finish. The nylon insert compresses against mating threads to resist loosening caused by vibration or dynamic loads, eliminating the need for additional locking hardware in most applications. The M5 x 0.80 thread size and right-hand thread direction conform to DIN 985 standards. At 5.00 mm in height with a width across flats of 8.00 mm, this nut is sized for compact fastening scenarios in light structural, mechanical, and equipment assemblies. Sold in a minimum order quantity of 50 pieces.

This nut is suited for metric fastening applications in industrial machinery, HVAC equipment frames, electrical enclosures, and general mechanical assemblies where vibration resistance is required. The zinc-plated finish provides basic corrosion resistance for indoor and protected outdoor environments. The DIN 985 standard designation makes it a direct fit in metric assemblies calling out that specification. Installation by maintenance technicians, millwrights, or mechanical contractors is typical.

Compatibility

Designed as a DIN 985-standard nylon insert hex lock nut for metric M5 x 0.80 threaded fastener assemblies in general industrial and mechanical applications.

Installation Notes

Installation requires a standard 8 mm wrench or socket. Power down and de-energize any equipment before servicing fastened assemblies. Nylon insert lock nuts are generally single-use — the locking torque of the nylon insert degrades after removal, so replace with a new nut rather than reusing. Follow applicable equipment manufacturer torque guidance for M5 fastener assemblies.
