Value Collection 342012 Hex Nut 1/4-20 Grade 2 Steel Unc

Product Description

The VALUE COLLECTION 342012 is a 1/4-20 hex nut manufactured from Grade 2 steel with a bright, uncoated finish. It features a right-hand thread in the UNC (Unified National Coarse) standard and carries a 2B thread fit class, making it a general-purpose fastener suited for a wide range of mechanical and structural assemblies. Width across flats measures 0.5 inches, and height is 11/64 inches. Hardness is rated between 68 HRB and 32 HRC. This nut is installed by electricians, plumbers, HVAC technicians, pipefitters, and general contractors wherever a standard 1/4-20 threaded connection is required.

This hex nut is appropriate for residential and light commercial applications including equipment mounting, conduit support, pipe hanger assemblies, panel fabrication, and general mechanical fastening. Its uncoated finish is suitable for dry indoor environments or applications where a finish coating is not required. The Grade 2 steel construction meets ASME B1.1 and ASME B18.2.2 standards, confirming dimensional and mechanical compliance for standard service conditions.
