Manufactured in accordance with Chinese national standard GB/T 5782, these hex bolts deliver consistent performance in both static and dynamic load environments.

If you're seeking fasteners that offer both mechanical precision and lasting durability, the GB-T 5782 hex head bolts should be your first choice.

What Are GB-T 5782 Hex Head Bolts?

GB-T 5782 hex head bolts are metric threaded fasteners with a full or partial thread and a standard hexagonal head for wrenching. This specification is the Chinese equivalent of ISO 4014/4017 and DIN 931/933, but designed with specific thread pitch and tolerances tailored to China’s industrial standards.

Used extensively in heavy machinery, metal structures, and automotive assemblies, the GB-T 5782 hex head bolts are engineered for high clamping force, easy torque application, and superior load-bearing capacity.

Top Benefits of GB-T 5782 Hex Head Bolts

1. Standardized Excellence

The GB-T 5782 hex head bolts conform to national standards, ensuring accurate dimensions, pitch, and material performance. Whether for domestic Chinese projects or international builds requiring compliance with GB norms, these bolts guarantee a trusted fit and finish.

2. Superior Strength and Reliability

Manufactured from high-grade carbon steel, alloy steel, or stainless steel, the GB-T 5782 hex head bolts are heat-treated for maximum strength. They can withstand shear, vibration, and axial load in high-stress environments, making them perfect for bridges, heavy-duty machinery, wind turbines, and steel frameworks.

3. Hex Head for Easy Torque Application

The six-sided head of the GB-T 5782 hex head bolts allows for simple installation using standard tools. This head style is favored for its ability to deliver high torque without slipping or rounding, making it a go-to for maintenance teams and engineers worldwide.

4. Corrosion Resistance Options

Available in finishes such as plain, black oxide, zinc-plated, hot-dip galvanized, or fully stainless steel (SS304/SS316), the GB-T 5782 hex head bolts can be tailored to resist corrosion even in marine or outdoor environments. Long service life = lower replacement and maintenance costs.

5. Wide Range of Sizes and Grades
