Value Collection 738170PS Hex Lock Nut M12x1.75

Product Description

The VALUE COLLECTION 738170PS is a metric hex lock nut designed to maintain clamping force in vibration-prone assemblies. It uses a distorted-thread locking style, which deforms a portion of the thread profile to create prevailing torque resistance without requiring a separate nylon insert or chemical adhesive. The nut is manufactured from Class 8 steel and carries a zinc finish for basic corrosion protection. With an M12x1.75 thread size and a 19.00 mm width across flats, this fastener fits standard M12 metric tooling and is suited for mechanical, structural, and equipment-assembly applications where a reliable self-locking nut is required.

This hex lock nut is appropriate for general industrial and trade applications involving metric fastener systems. It is commonly used in HVAC equipment frames, pump and motor mounting assemblies, light structural fabrication, and similar environments where vibration or dynamic loading could loosen a standard hex nut. The right-hand thread direction is consistent with standard metric fastener practice. Right-hand installation requires no special procedures beyond standard metric wrenching. This nut meets DIN 980 and ISO 7042 standards, making it suitable for applications where conformance to those fastener specifications is required.

Key Features

• Distorted-thread locking style provides prevailing torque resistance without inserts or adhesives
• M12x1.75 metric thread size with right-hand thread direction
• Class 8 steel construction for high-strength metric fastener applications
• Zinc finish for basic corrosion resistance in dry or mildly humid environments
• Conforms to DIN 980 and ISO 7042 fastener standards
• 19.00 mm width across flats compatible with standard metric hex tooling

Compatibility

Designed as a standard metric replacement or new-installation hex lock nut for any M12x1.75 threaded fastener application conforming to DIN 980 or ISO 7042 specifications.

Installation Notes

Installation is performed with a standard metric wrench or socket sized for 19.00 mm across flats. Power down or de-energize any equipment before accessing fastener locations on live assemblies. Distorted-thread prevailing torque nuts are single-use by design in critical applications — once the locking feature has been engaged and removed, replace with a new nut to ensure reliable locking performance. No special tools beyond standard metric wrenching equipment are required for installation.
