Value Collection CD557230 Hex Lock Nut 1-1/4-12 Unf Grade B 10pk

Product Description

The VALUE COLLECTION CD557230 is a 1-1/4-12 UNF Grade B hex lock nut with a nylon insert, designed to maintain fastener position under vibration and torque load. Constructed from steel with a zinc-plated finish for basic corrosion resistance, this nut features a prevailing-torque nylon insert that grips the mating thread without deforming the fastener. The width across flats measures 1-13/16 inches and the overall height is 1-25/64 inches. Sold in a package of 10, this part is suited for general mechanical, industrial, and light structural assembly applications where thread locking without adhesive is required.

This hex lock nut is appropriate for use in general industrial assembly, mechanical equipment, and maintenance applications requiring a reliable UNF thread lock. The 1-1/4-12 UNF thread pitch is a fine-thread specification commonly found in precision mechanical assemblies, hydraulic fittings, and heavy equipment fastening. The nylon insert style is appropriate where reusable, non-permanent locking is preferred over chemical threadlockers. Installers working in HVAC equipment frames, pump assemblies, and similar trade equipment will find this nut a direct-fit option for standard UNF fastener locations.

Installation Notes

Installation is performed by hand and standard wrench using a 1-13/16-inch hex wrench or socket. Power down or de-energize any equipment before accessing fastener locations in live mechanical or electrical assemblies. Do not reuse nylon insert lock nuts in safety-critical applications where the insert shows visible wear or deformation. Follow applicable equipment manufacturer torque specifications and relevant codes for the assembly type.
