Value Collection 41764 Hex Lock Nut M12x1.5 Class 8 Zinc

Product Description

The VALUE COLLECTION 41764 is a metric hex lock nut with a nylon insert locking mechanism, designed to resist loosening under vibration and torque loads. Manufactured from Class 8 steel with a zinc-plated finish, this nut meets DIN 985 standards. The M12x1.5 thread size and right-hand thread direction make it a standard fastener for metric assemblies across industrial, mechanical, and structural applications. Measuring 12.00 mm in height and 19.00 mm across the flats, it is installed using standard metric wrenching tools. Machinists, millwrights, maintenance technicians, and general contractors commonly spec this fastener.

This nylon insert lock nut is suited for metric fastening applications in light to medium-duty mechanical assemblies where vibration resistance is required. The nylon collar deforms around the mating thread, creating a friction-based lock that holds without requiring a secondary locking feature such as a jam nut or thread-locking compound. Typical use cases include equipment mounting, frame assemblies, and machinery maintenance across manufacturing, construction, and general trade environments.

Key Features

• Nylon insert locking style prevents self-loosening under vibration without secondary fasteners
• Class 8 steel construction provides reliable tensile and proof load capacity for metric assemblies
• Zinc-plated finish offers basic corrosion resistance for general-purpose indoor and light outdoor use
• Right-hand M12x1.5 thread conforms to DIN 985 for broad metric hardware compatibility
• 19.00 mm width across flats accepts standard metric hex wrenches and sockets

Compatibility

Designed as a DIN 985-compliant replacement or standard-service hex lock nut for metric M12x1.5 threaded fastener applications in mechanical and structural assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated metric torque wrench sized for a 19 mm hex. Always ensure mating bolt or stud threads are clean and free of damage before installation. Nylon insert lock nuts are generally rated for single use — the nylon collar loses clamping effectiveness after removal and should not be reused in critical applications. Follow applicable equipment manufacturer torque specifications and relevant industry standards for the assembly being serviced.
