Zoro Select N04120.050.0001 Hex Nut 1/2"-13 Grade 8 Steel Black Oxide

1/2"-13 Grade 8 Hex Nut

This hex nut is a Grade 8 steel fastener with a black oxide finish. It follows ASME B18.2.2 dimensional standards and uses a right-hand UNC thread. The pack contains fifty pieces for maintenance or assembly tasks.

UNC Thread and Grade 8 Limits

The UNC thread series provides standard coarse engagement for general fastening. Grade 8 strength suits high-stress joints but requires matching Grade 8 bolts and proper torque. Over-torquing or mixing grades reduces clamp load and can strip threads.

Fifty-Piece Pack Capacity

A fifty-piece pack covers multiple connection points on heavy equipment or structural frames. It runs out on large projects that need hundreds of fasteners or on jobs requiring different thread sizes. Buyers needing metric threads or finer pitch must source separate hardware.
