Hot Forged Hex Nut | Heavy-Duty Hex Nuts
A hex nut is one of the most widely used fasteners in mechanical assemblies, known for its versatility, strength, and reliable threaded connection. Weforging specializes in hot forged hex nuts designed for high load capacity, stable tightening performance, and long service life. Manufactured through controlled forging, precision machining, and strict quality testing, our hex nuts deliver excellent consistency for demanding industrial applications. Whether you require standard sizes or customized dimensions, we support global OEM customers with flexible and efficient production solutions.
What Is a Hex Nut?
A hex nut is a six-sided fastener used together with bolts or threaded rods to secure mechanical components. Its geometric shape ensures easy wrenching from multiple angles and offers high torque resistance.
Compared with other nut types, hex nuts provide a balanced combination of strength, simplicity, and cost-efficiency. Heavy-duty versions, such as heavy hex nuts, are used when higher preload and structural strength are required.
They are commonly measured by industry standards, including hex nut sizes defined in DIN, ISO, ANSI, and GB specifications.
Manufacturing Process
Weforging’s hex nuts are produced through a fully controlled hot forging process to ensure superior density and mechanical reliability:
Raw material cutting
Induction heating and die forging
Flash removal and trimming
CNC machining for threads and surfaces
Heat treatment for increased hardness and strength
Surface finishing (zinc plating, black oxide, Dacromet, etc.)
100% inspection before shipment
This process guarantees uniform shape, stable dimensions, and excellent load-bearing capability.
