Value Collection HNI2137-005BX Hex Nut 1-3/8-6 Unc Grade 2

Product Description

The VALUE COLLECTION HNI2137-005BX is a 1-3/8-6 UNC hex nut manufactured from Grade 2, Grade A steel with a bright uncoated finish. It features a right-hand thread and measures 2-1/16 inches across the flats with a height of 1-11/64 inches. The nut weighs 0.28 pounds per piece and is intended for general-purpose fastening applications where a standard-duty, non-coated steel nut is specified. Electricians, plumbers, pipefitters, HVAC technicians, and general mechanical contractors commonly use this nut size in structural and equipment-mounting assemblies.

This hex nut is suited for use in residential and light commercial construction, mechanical rooms, equipment pads, and utility installations where 1-3/8-inch coarse-thread fasteners are called for. The UNC thread standard ensures broad compatibility with readily available threaded rod, bolts, and studs of the same size and pitch. The uncoated finish is appropriate for indoor or protected environments where corrosion resistance is not a primary requirement.
