Value Collection 440031 8-32 Unjc Hex Lock Nut 50-pack

Product Description

The VALUE COLLECTION 440031 is an 8-32 UNJC hex lock nut with an expanding flex top, manufactured from 18-8 stainless steel and supplied in an uncoated finish. The expanding flex top design provides prevailing-torque locking action without the need for adhesives or separate lock washers, making it suitable for vibration-prone assemblies. This nut meets IFI 100/107 and NASM 25027 standards, confirming compliance with military and industrial fastener specifications. Licensed tradespeople and assembly technicians working on precision or aerospace-adjacent applications will find this part appropriate for threaded joint retention in stainless-compatible environments.

The 440031 is used in applications where 8-32 UNJC thread engagement is required and corrosion resistance is a priority. The 18-8 stainless steel construction makes it a practical choice for marine, food-service, or outdoor enclosure assemblies. The expanding flex top allows repeated installation and removal cycles while maintaining locking torque. This part is packaged in quantities of 50, suitable for shop stock or small-batch production runs.

Compatibility

Designed for use in assemblies requiring 8-32 UNJC threaded fasteners where a prevailing-torque hex lock nut with stainless steel construction and military-specification compliance is specified.

Installation Notes

Installation is typically performed by mechanical assemblers, maintenance technicians, or sheet-metal tradespeople using standard hex tooling sized for the fastener. Always verify that the mating threaded component uses a compatible UNJC thread form before installation. De-energize and isolate any assembly before performing fastener work on electrical enclosures or powered equipment. Do not exceed the rated torque for the thread size and material as specified in applicable engineering documentation.
