Value Collection 525036PS M5x0.8 L-lock Hex Nut Zinc Steel

Product Description

The VALUE COLLECTION 525036PS is a K-lock hex nut with an integrated external tooth lock washer, designed for metric fastening applications requiring reliable vibration resistance. Manufactured from steel with a zinc plating finish, this M5x0.8 nut measures 8 millimeters across flats and features a 9.5-millimeter washer diameter. The external tooth configuration bites into the mating surface as the fastener is torqued, providing mechanical resistance against loosening. This part is suited for use by electricians, HVAC technicians, mechanical contractors, and general trade professionals working with metric-threaded assemblies.

This K-lock nut is appropriate for residential and light commercial applications where a single fastener component combines the hex nut and lock washer function. It is commonly used in panel mounting, equipment enclosures, and mechanical assemblies that see vibration or thermal cycling. The M5x0.8 metric thread standard makes it compatible with standard metric hardware across a range of trade and industrial equipment.

Key Features

• Integrated external tooth lock washer eliminates the need for a separate lock washer
• M5x0.8 metric thread for compatibility with standard metric fastener systems
• Zinc plated steel construction provides corrosion resistance in typical indoor environments
• 8 millimeter width across flats fits standard metric hex drivers and wrenches
• 9.5 millimeter washer diameter distributes clamping load across the mating surface

Compatibility

Designed as an OEM-style replacement or standard-stock metric fastener for M5x0.8 threaded applications in electrical, HVAC, and mechanical assemblies.

Installation Notes

Installation requires a standard metric hex wrench or socket sized for 8 millimeter across flats. De-energize or power down any electrical equipment before fastening hardware near live components. Do not reuse lock nuts in critical applications after removal, as the locking teeth may be compromised. Follow applicable NEC or equipment manufacturer torque guidelines for the assembly being serviced.
