Value Collection KP78603 Hex Lock Nut M10 X 1.50 Grade 8.8

Product Description

The VALUE COLLECTION KP78603 is a metric hex lock nut engineered with a distorted thread locking style to resist loosening under vibration and dynamic loads. Built to Grade 8.8 steel with a zinc-plated finish for corrosion resistance, this nut conforms to DIN 980 standards. The M10 x 1.50 thread size and right-hand thread direction make it a straightforward fit for common metric fastening applications. Each package contains 50 nuts. Mechanical contractors, millwrights, pipefitters, and general maintenance technicians working with metric hardware will find this nut suitable for a wide range of structural and mechanical assemblies.

This hex lock nut is suited for use in residential and commercial mechanical installations, industrial equipment maintenance, and structural assemblies where metric fasteners are required. The distorted thread design creates prevailing torque without the need for a nylon insert or separate locking element, making it appropriate for applications exposed to heat or environments where nylon-insert nuts are not suitable. It is commonly used in HVAC equipment frames, pump and motor mounts, and general sheet metal or fabricated steel assemblies.

Key Features

• Distorted thread locking style provides prevailing torque without nylon inserts, suitable for elevated-temperature applications
• Grade 8.8 steel construction meets DIN 980 fastener standard
• Zinc-plated finish provides corrosion resistance for indoor and moderate-exposure environments
• M10 x 1.50 metric thread with right-hand direction for standard metric bolt compatibility
• 10 mm height and 17 mm width across flats for use with standard metric wrenches
• Sold in a package of 50 nuts to support job-site and shop stocking needs

Compatibility

Designed as an OEM-style replacement or stock fastener for metric assemblies requiring an M10 x 1.50 prevailing torque hex lock nut conforming to DIN 980.

Installation Notes

Installation should be performed by a qualified mechanical technician or tradesperson familiar with metric fastener standards. De-energize and lock out any equipment before servicing fastened assemblies. Use a standard metric wrench or socket sized for 17 mm across flats. Do not reuse prevailing torque lock nuts that have been removed, as distorted thread locking effectiveness diminishes after the first installation cycle.
