Value Collection C84739 Hex Lock Nut M10 X 1.25 Din 985 25pk

Product Description

The VALUE COLLECTION C84739 is a metric hex lock nut with a nylon insert locking mechanism, manufactured from Grade 8 steel with a zinc-plated finish. The nylon insert deforms around mating threads under torque, creating resistance to vibration-induced loosening without damaging the bolt or stud. The nut is threaded M10 x 1.25 with a right-hand thread direction and meets DIN 985 standards. Each unit measures 10.00 millimeters in height with a width across flats of 17.00 millimeters and a width across points of 18.90 millimeters. This fastener is used in mechanical assembly, structural, and equipment maintenance applications by millwrights, maintenance technicians, and mechanical contractors.

This nut is suited for metric fastening applications where vibration resistance is required. The DIN 985 standard makes it a common choice in industrial machinery, automotive components, and general fabrication work. The zinc-plated finish provides a baseline level of corrosion resistance for use in moderately exposed environments. Each package contains 25 nuts, making it appropriate for both single-use repair situations and small production runs.

Key Features

• Nylon insert locking style per DIN 985 — resists loosening under vibration without damaging mating threads
• Grade 8 steel construction for high tensile strength fastening applications
• Zinc-plated finish provides corrosion resistance in moderate service conditions
• M10 x 1.25 right-hand metric thread — fine pitch for improved thread engagement
• Width across flats of 17.00 millimeters, compatible with standard metric tooling
• Sold in a package of 25 units with a minimum order quantity of 1 package

Compatibility

Designed for use with M10 x 1.25 metric bolts and threaded studs in applications conforming to DIN 985 fastener standards.

Installation Notes

Installation is performed by hand-starting the nut onto a clean, undamaged male thread, then driving to the specified torque using a standard metric wrench or socket. Power down or de-energize any equipment before fastener service on mechanical assemblies. Nylon insert lock nuts are generally rated for single use — once the insert has been compressed, locking effectiveness is reduced on reuse. Follow applicable mechanical codes and equipment manufacturer guidelines for torque specifications.
