Hex Nut

This hex nut is the most widely used standard threaded fastener, matched with hex bolts to clamp and fix various metal and non-metal workpieces. It features six flat symmetrical outer sides for easy tool operation.

Manufactured from medium carbon steel, the nut undergoes blue white zinc electroplating treatment to form a bright anti-rust coating, resisting oxidation and mild moisture corrosion for indoor and light outdoor working environments. Strength grade markings can be printed on the hex surface for quick quality identification during assembly.

The hexagonal outer profile fits all standard open-end spanners and socket wrenches, enabling stable torque control during tightening. Precisely rolled internal threads deliver smooth matching with standard metric bolts, maintaining consistent clamping force after repeated disassembly and fastening cycles. Uniform wall thickness ensures balanced stress distribution to avoid deformation under medium and heavy loads.

Hex nuts are universally applied across mechanical manufacturing, engineering construction, automobile assembly, home appliance production and pipeline connection. It serves as the basic supporting fastener for most bolted connection structures.

We provide full customized solutions: adjustable thread pitch, nut thickness, surface treatment and engraved brand logos for machinery factories, construction hardware distributors and auto parts suppliers.

All finished hex nuts undergo strict pre-delivery inspections, including dimensional measurement, thread precision test, hardness test and plating uniformity check, to guarantee stable thread fit and reliable mechanical strength for every production batch.
