Heavy Hex Head Bolt | Hex Bolt Manufacturer

One of the most popular choices for applications like steel structures and machinery is the Heavy Hex Head Bolt, a powerful fastening solution that can handle high loads and extreme conditions.

What is a heavy hex head bolt?

Heavy Hex Head Bolt derives its name from its shape, which has a wider head and thicker shank compared to standard hex bolts. This design provides a larger bearing surface and greater clamping force, making heavy hex head bolt ideal for heavy duty applications that require a strong and reliable fastening solution.

Where are most heavy hex head bolts used?

Heavy Hex Head Bolts are most commonly used in construction, infrastructure, and mechanical industries, where they help assemble critical components such as bridge girders, machinery frames, and pipelines etc. Heavy hex head bolt is also a preferred choice for applications that require high torque values, as their wider head design allows for better wrench grip and increased torque capacity.

Why should we use heavy hex head bolt?

One of the key advantages of Heavy Hex Head Bolts is their exceptional resistance to fatigue and shear forces. This is due to their thicker shank and higher tensile strength, which allow them to withstand extreme loads and vibrations. Also, heavy hex head bolts are available in a range of materials, including high strength alloys, stainless steel and titanium, making them suitable for use in corrosive and high-temperature environments.

What is the difference between hex and heavy hex head bolts?

Standard hex bolt has a smaller head and with lighter weight when compared with heavy hex head bolt. For most industrial and construction applications, standard hex bolts DIN931, DIN933, ISO4014, ISO4017 would be good choice, while for steel structure, bridge construction and heavy machinery, heavy hex head bolt is the best choice.

What grade are heavy hex bolts?

Heavy hex bolts, also known as heavy hex head bolts or hex structural bolts. The most common seed heavy hex bolts grades are grade 5, 8, 8.8, 10.9, 12.9, ASTM A193 B7, A325, A490, A307 etc. Ningbo Fastenwell manufacture and export heavy hex bolts upon your request, especially ASTM A193 B7, A325, A307, A490 with heavy hex nuts A194 2H.
