Value Collection 440012 Hex Lock Nut Grade 2 Steel 100 Pack

Product Description

The VALUE COLLECTION 440012 is a hex lock nut with an expanding flex top locking style, manufactured from Grade 2 steel with a cadmium finish. It is designed to maintain secure thread engagement under vibration and load cycling in mechanical and structural assemblies. The nut measures 0.2430 inches in height, 0.3760 inches across flats, and 0.4190 inches across points, with a flange diameter of 0.3670 inches. The right-hand thread with a 3B fit class meets IFI 100/107 and NASM 25027 standards, including military specification requirements. Licensed trades and maintenance technicians working on equipment assemblies, brackets, and mechanical fastening applications will find this nut suited to standard inch-system hardware.

This hex lock nut is intended for use in general industrial, mechanical, and structural fastening applications where vibration resistance is required. The expanding flex top locking mechanism provides prevailing torque without the need for separate locking hardware such as washers or thread inserts. It is compatible with inch-system threaded fasteners and is sold in a package quantity of 100 units, making it practical for production or service environments requiring consistent hardware on hand.
