Value Collection C764207 M12x1.75 Hex Lock Nut Grade 8 Zinc

Product Description

The VALUE COLLECTION C764207 is a metric hex lock nut designed to maintain fastener tension in high-load applications where vibration or dynamic stress could cause loosening. The distorted-thread locking style creates mechanical interference when the nut is torqued onto a mating bolt, eliminating the need for separate locking inserts or adhesives. Manufactured from Grade 8 steel with a zinc-plated finish, this nut delivers strong corrosion resistance and the mechanical strength required for structural and heavy-duty assembly work. The M12x1.75 thread size and 11 mm height conform to DIN 980 and ISO 7042 standards. Each package contains 50 nuts. Licensed trades and industrial maintenance technicians are the primary installers.

This hex lock nut is suited for metric fastener applications in industrial machinery, structural steel assemblies, automotive fabrication, and mechanical equipment maintenance. The right-hand thread direction is standard for most metric bolt patterns. The zinc coating provides surface protection in environments with moderate moisture exposure. The distorted-thread design makes this nut a single-use locking fastener in most assemblies, as the locking interference is reduced after initial installation and removal. Package quantity of 50 supports both job-site and shop-floor use.

Key Features

• Distorted-thread locking style provides mechanical resistance to loosening without secondary hardware
• Grade 8 steel construction for high tensile strength in heavy-duty fastener applications
• Zinc-plated finish for moderate corrosion resistance
• M12x1.75 metric thread size with right-hand thread direction
• Conforms to DIN 980 and ISO 7042 dimensional and performance standards
• Packaged in quantities of 50 for production and maintenance use

Compatibility

Designed for use with M12x1.75 metric bolts and threaded fastener assemblies conforming to DIN 980 and ISO 7042 standards.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or mechanical assemblers using standard metric wrenches or sockets. Power down and de-energize any equipment before fastener replacement on live machinery. Distorted-thread lock nuts are generally intended for single-use applications, as the locking interference decreases with repeated removal and reinstallation. Follow applicable equipment manufacturer torque specifications and relevant industry fastener standards when determining final torque values.
