Value Collection MP41754 M8 X 1.25 Hex Lock Nut Din 985

Product Description

The VALUE COLLECTION MP41754 is a metric hex lock nut with a nylon insert locking mechanism, designed to resist vibration-induced loosening in bolted assemblies. Built from Class 8 steel with a zinc-plated finish, this nut meets DIN 985 standards for nylon insert lock nuts. The M8 x 1.25 thread size and right-hand thread direction make it a standard choice for a wide range of mechanical and structural fastening applications. The nylon insert grips the mating bolt thread to maintain clamp load under dynamic loading conditions. Maintenance technicians, millwrights, and general contractors install these as part of routine assembly and repair work across industrial and commercial settings.

This nylon insert hex lock nut is suited for metric-threaded fastening applications in HVAC equipment mounting, electrical enclosure assembly, plumbing fixture supports, and general mechanical fabrication. The zinc-plated finish provides basic corrosion resistance for indoor and light-duty outdoor environments. The DIN 985 standard ensures dimensional consistency, making it compatible with standard M8 metric hardware across a broad range of equipment and structural assemblies.

Key Features

• Nylon insert locking style resists loosening from vibration and dynamic loads
• Class 8 steel construction for reliable tensile strength in metric fastening applications
• Zinc-plated finish provides basic corrosion resistance for general-use environments
• Right-hand thread direction, M8 x 1.25 pitch, compatible with standard M8 bolts and studs
• Conforms to DIN 985 fastener standard for consistent dimensional tolerances

Compatibility

Designed as a standard DIN 985 nylon insert hex lock nut for use with M8 x 1.25 right-hand threaded bolts and studs in metric fastening applications.

Installation Notes

Install and remove using a standard metric wrench or socket sized for a 13 mm width across flats. De-energize or shut down any equipment before servicing fastened assemblies. The nylon insert is a single-use locking element and should not be reused after removal, as the insert loses clamping effectiveness with repeated cycling. Follow applicable mechanical assembly codes and equipment manufacturer torque guidance for the specific joint being fastened.
