Value Collection 738040PS M4x0.7 Hex Lock Nut Class 8 Zinc

Product Description

The VALUE COLLECTION 738040PS is a distorted-thread hex lock nut engineered for M4x0.7 metric fastening applications. It is manufactured from Class 8 steel with a zinc finish that provides basic corrosion resistance in standard service environments. The nut measures 7.00 mm across flats and 7.66 mm across points, with a height of 3.70 mm. The distorted-thread locking style creates resistance to vibration-induced loosening without requiring a secondary locking element such as a patch or insert. This nut is installed by electricians, HVAC technicians, plumbers, and mechanical assemblers wherever a compact, reliable metric lock nut is needed on M4 fastener assemblies.

This hex lock nut is suited for use in light-duty mechanical assemblies, electrical enclosures, HVAC equipment panels, and plumbing fixture brackets where M4 metric threaded fasteners are specified. The right-hand thread direction follows standard installation practice. The zinc finish is appropriate for dry to mildly humid indoor environments. The distorted-thread design allows for tool-driven installation without adding height or bulk to the assembly stack.

Key Features

• Distorted-thread locking style resists loosening under vibration without adhesives or secondary hardware
• M4x0.7 metric thread size with right-hand thread direction
• Class 8 steel construction for reliable strength in light-duty fastening
• Zinc finish provides basic corrosion protection for indoor service conditions
• Compact profile: 7.00 mm across flats, 3.70 mm height
• Meets DIN 980 and ISO 7042 fastener standards

Compatibility

Designed as a standard metric replacement or service nut for any M4x0.7 threaded fastener application requiring a distorted-thread hex lock nut per DIN 980 or ISO 7042.

Installation Notes

Install with a standard metric hex wrench or socket sized for 7.00 mm across flats. Power down and de-energize any electrical assembly before servicing fasteners within enclosures or control panels. The distorted-thread design is intended for single-use installation; do not reuse a removed distorted-thread nut where vibration resistance is critical. Follow applicable assembly standards and equipment manufacturer torque guidelines for M4 fasteners in the specific application.
