Value Collection 440011 Hex Lock Nut 1-8 Grade 2 Cadmium 5-pack

Product Description

The VALUE COLLECTION 440011 is a 1-8 threaded hex lock nut with an expanding flex-top locking style, designed to maintain secure fastening under vibration and dynamic load conditions. Manufactured from Grade 2 steel with a cadmium finish for corrosion resistance, this nut meets MIL-S-7742 military specifications. The right-hand thread and 2B thread fit class make it a standard-compatible choice for structural and mechanical assemblies. Licensed tradespeople and maintenance technicians working on military-spec, industrial, or heavy mechanical equipment will find this nut suited to demanding fastening applications. Each package contains 5 nuts.

This hex lock nut is intended for use in mechanical assemblies requiring a reliable, vibration-resistant connection at a 1-8 thread size. The expanding flex-top locking mechanism engages the mating thread to resist back-off without requiring a secondary locking element such as a washer or adhesive. Typical applications include industrial machinery, maintenance and repair operations, and military or government equipment that mandates MIL-S-7742 compliance. Installation is performed by qualified mechanics or trades professionals using standard hex tooling appropriate for a 1-7/16 inch across-flats dimension.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a standard hex wrench or socket sized for a 1-7/16 inch across-flats dimension. Ensure the mating threaded shaft is clean, free of damage, and matches the 1-8 right-hand thread specification before installation. De-energize or lock out any equipment per applicable safety procedures before fastener service. Do not exceed the torque limits appropriate for Grade 2 steel fasteners as specified by the relevant engineering or maintenance documentation for the assembly.
