Value Collection 812040PR Hex Lock Nut M8x1.25 Din 985

Product Description

The VALUE COLLECTION 812040PR is a metric hex lock nut with a nylon insert locking mechanism, designed to resist loosening under vibration and dynamic loads. Built from Class 8 steel with a zinc finish for corrosion resistance, this nut follows the DIN 985 standard. The M8x1.25 thread size and right-hand thread direction make it a straightforward fit for standard metric fastening applications. With a width across flats of 13.00 mm and a height of 8.00 mm, it is sized for use with standard hex wrenches and sockets. Electricians, HVAC technicians, plumbers, and general tradespeople commonly use this type of hardware in equipment assembly, panel mounting, and mechanical installations.

This nylon insert lock nut is suited for both residential and light commercial applications where vibration or thermal cycling could compromise standard nut retention. Common install scenarios include securing mounting brackets, motor assemblies, equipment panels, and structural fasteners in mechanical and electrical systems. The zinc finish provides a base level of corrosion protection appropriate for indoor and sheltered outdoor environments. This nut is sold individually but requires a minimum order quantity of 100 pieces.

Key Features

• Nylon insert locking style resists loosening from vibration without damaging mating threads
• Class 8 steel construction provides solid tensile strength for general metric fastening
• Zinc finish offers corrosion protection for indoor and sheltered applications
• Conforms to DIN 985 standard for consistent dimensional and performance compliance
• Right-hand thread direction compatible with standard metric fastener assemblies
• Width across flats of 13.00 mm fits standard metric hex tooling

Compatibility

Designed for use with M8x1.25 metric bolts and threaded rod conforming to DIN 985 dimensional standards. Suitable as a general-purpose nylon insert lock nut in metric fastener assemblies.

Installation Notes

Installation requires a standard metric hex wrench or socket sized for 13.00 mm across flats. Nylon insert lock nuts are single-use by design — the nylon collar deforms on first installation and should not be reused after removal. Ensure the mating bolt or stud is free of debris and damage before installation to avoid compromising the nylon insert. Follow applicable mechanical or electrical codes for fastener torque requirements specific to the assembly being serviced.
