Value Collection NL580080Z-025B M8x1.25 Hex Lock Nut 25pk

Product Description

The VALUE COLLECTION NL580080Z-025B is a metric hex lock nut with a nylon insert locking mechanism, manufactured from Class 8 steel. It carries an M8x1.25 thread size and conforms to ASME B 18.16.6 standards. The nylon insert compresses against the bolt threads upon installation, creating resistance to loosening from vibration and dynamic loads. This fastener is sold in a minimum quantity of 25 pieces per order. Electricians, HVAC installers, plumbers, and general mechanical contractors use this style of lock nut where a reliable, reusable locking solution is required without the need for thread-locking compounds.

This hex lock nut is suited for metric threaded fastener applications in both residential and light commercial mechanical systems. It is commonly used in equipment mounting, bracket assemblies, panel attachment, and anywhere an M8x1.25 threaded stud or bolt requires a secure, vibration-resistant connection. The Class 8 steel construction makes it appropriate for moderate-to-high-load fastening applications across HVAC equipment frames, electrical enclosures, plumbing fixtures, and general fabrication work.

Installation Notes

Installation should be performed with the appropriate metric hex wrench or socket. Ensure the mating bolt or stud is clean and free of damage before threading the nut. Nylon insert lock nuts can be reused a limited number of times before the insert loses effective clamping force and should be replaced. Power down or de-energize any equipment before performing fastener service in electrical or control panel assemblies.
