Value Collection KP66135 Hex Lock Nut 7/8-9 Grade C 20 Pack

Product Description

The VALUE COLLECTION KP66135 is a 7/8-9 UNC hex lock nut with a distorted-thread locking style, manufactured from Grade C steel with a zinc-plated and wax finish. The distorted-thread design creates mechanical interference on engagement, resisting loosening under vibration and dynamic loads without requiring a secondary locking element. This is a right-hand thread fastener sized to 7/8-9 UNC, suitable for general structural and mechanical assembly applications. Licensed trades and maintenance professionals use this nut where reliable thread retention is needed in standard inch-system fastener installations.

This hex lock nut is suited for residential and commercial maintenance, construction, and equipment assembly where UNC fastener standards apply. The zinc-plated with wax finish provides a base level of corrosion resistance appropriate for indoor and mildly exposed environments. Sold in a package quantity of 20, the KP66135 is a practical stocking item for shops, service vans, and maintenance departments that regularly work with 7/8-9 UNC hardware.

Key Features

• Distorted-thread locking style resists loosening from vibration without additional hardware

Compatibility

Designed as a standard UNC-thread hex lock nut for use with 7/8-9 right-hand threaded fasteners in general mechanical and structural assembly applications.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or journeymen in the applicable trade. Verify mating bolt thread specification matches 7/8-9 UNC before installation. Use an appropriately sized open-end or box wrench to drive the nut to the assembly torque required by the joint design. Distorted-thread lock nuts are generally single-use — inspect the locking element after removal and replace if the interference fit is reduced.
