It features a right-hand thread in the UNC (Unified National Coarse) standard and conforms to ASME B1.1 and ASME B18.2.2 dimensional and thread specifications. The nut measures 1.0625 inches across flats and carries a Thread Fit Class of 2B, making it suitable for general-purpose fastening in structural, mechanical, and utility assemblies. Hardness ranges from 68 HRB to 32 HRC. Plumbers, pipefitters, HVAC installers, electricians, and general mechanical contractors routinely use this fastener in everyday service and repair work.

This hex nut is appropriate for use in residential and light commercial construction, mechanical assemblies, equipment mounting, and general trade service applications. The 5/8-11 thread size is common in structural connections, equipment frames, pipe hangers, and utility mounting hardware. It is sold individually but requires a minimum order of 50 pieces per order.
