Product Identity

The Zoro Select hex nut is a Grade 5 steel fastener with a 3/8"-16 UNC thread and zinc-plated finish. It is sold in a pack of 100 pieces for maintenance, repair, and assembly tasks requiring inch-series hardware.

Build Integration

Each nut has a 9/16 in hex width and a 21/64 in height to fit standard wrenches and thread depths. The right-hand UNC thread matches common bolts and studs, while the zinc plating resists corrosion in indoor and sheltered outdoor environments.

Thermals and Power

As a passive mechanical component, the nut generates no heat, draws no power, and produces no noise during installation or service. Rockwell hardness ranges from C19 to C30 to maintain clamp load under normal vibration and thermal cycling.
