Value Collection 41754 M8 X 1.25 Hex Lock Nut Nylon Insert

Product Description

The VALUE COLLECTION 41754 is a metric hex lock nut with a nylon insert, designed to resist loosening under vibration and dynamic loads. Built from Class 8 steel with a zinc-plated finish, this nut meets DIN 985 standards and carries an M8 x 1.25 thread size. The nylon insert deforms around the mating thread to create a prevailing-torque locking action without requiring adhesives or secondary locking hardware. Right-hand thread direction follows standard metric convention. Installed by machinists, maintenance technicians, and assembly professionals across general industrial, automotive, and mechanical applications.

This nut is suited for metric fastening applications where vibration resistance is required. Common installation scenarios include machinery frames, automotive components, equipment panels, and structural assemblies that see repeated movement or shock loading. The zinc-plated finish provides basic corrosion resistance in indoor and light-duty environments. It is sold individually with a minimum order quantity of 50 pieces, making it appropriate for maintenance shops and production environments maintaining metric hardware stock.

Key Features

• Nylon insert provides prevailing-torque locking action without adhesives
• Class 8 steel construction for reliable strength in metric fastening applications
• Zinc-plated finish for corrosion resistance in indoor and light-duty environments
• M8 x 1.25 right-hand thread conforms to DIN 985 fastener standard
• Hex drive profile compatible with standard metric wrenches and sockets

Compatibility

Designed as a DIN 985-compliant replacement or stock hardware item for metric M8 x 1.25 threaded fastener applications in general industrial, automotive, and mechanical assembly work.

Installation Notes

Install using a standard metric wrench or socket sized for 13 mm across flats. Ensure the mating bolt or stud is clean and free of damage before seating the nylon insert. Power down or de-energize any equipment before accessing fastener locations in mechanical or electrical assemblies. Nylon insert lock nuts are generally considered single-use; replace the nut if the nylon insert has been previously compressed, as locking effectiveness decreases with reuse.
