Value Collection KP78602 Hex Lock Nut M8 X 1.25 Grade 8.8

Product Description

The VALUE COLLECTION KP78602 is a metric hex lock nut designed with a distorted thread locking style to resist loosening under vibration and dynamic loads. Manufactured to Grade 8.8 steel and finished with a zinc plating for corrosion resistance, this nut conforms to DIN 980 standards. The M8 x 1.25 thread size and right-hand thread direction make it a straightforward replacement or new-installation fastener for general mechanical assemblies. Each package contains 50 nuts. This fastener is appropriate for maintenance technicians, millwrights, and mechanical contractors working on equipment requiring reliable thread retention.

This hex lock nut is suited for use in general industrial, commercial, and light mechanical applications where standard hex nuts are insufficient and a positive thread-locking solution is required without the use of separate lock washers or thread-locking compounds. The distorted thread profile creates interference with the mating bolt thread to maintain clamp load. Typical applications include machinery frames, equipment panels, HVAC equipment mounting, and structural assemblies where metric M8 fasteners are specified.

Key Features

• Distorted thread locking style resists loosening from vibration without requiring separate hardware
• Grade 8.8 steel construction provides reliable mechanical strength for general-purpose metric fastening
• Zinc-plated finish offers basic corrosion resistance for indoor and light-duty outdoor use
• Conforms to DIN 980 fastener standard for consistent dimensional and performance compliance
• Right-hand thread direction for standard bolt engagement
• Sold in a 50-piece package to support production, maintenance, and repair inventory

Compatibility

Designed for use with M8 x 1.25 metric bolts and threaded rods conforming to standard metric thread profiles. Suitable as an OEM-style replacement or new-installation lock nut wherever a DIN 980 Grade 8.8 distorted thread hex lock nut is specified.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians using appropriately sized metric wrenches or sockets. De-energize and lock out any equipment before fastener service to prevent injury. Distorted thread lock nuts are single-use by design and should not be reused after removal, as the locking interference is reduced once the nut has been torqued. Follow applicable equipment manufacturer specifications and relevant mechanical codes for proper torque values.
