Heavy Hex Bolts

Heavy Hex Bolts, Standard heavy hex structural bolts, ASTM A307 ASTM A325 and A490 grade specifications, low and medium carbon steel, alloy, and stainless steel bolts bolting China supplier

Heavy hex bolts have a head that is larger than a standard (finish) hex head. Standard heavy hex structural bolts are made of low to mid carbon steel. The large head offers a greater bearing surface that distributes the clamping load over a greater area.

Heavy Hex Bolt are designed for use in a variety of high temperature, high strength industrial applications, such as with steel fabrication and general construction. They feature a thicker head than standard or regular hex bolts, and offer a greater bearing surface that distributes the clamping load over a wider area. Heavy hex bolt can be made with a few different materials including low and medium carbon steel, alloy, and stainless steel, and are available plain, hot dipped galvanized, phosphate, zinc or cadmium plated. Some sizes of heavy hex bolt are fully threaded while other sizes offer a smooth shoulder area.

The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C which denote tensile strength, configuration, and application.

Standard Thread Lengths
Bolt lengths ≤ 6″: Thread length = (2 X diameter) + 1/4″Bolt lengths > 6″: Thread length = (2 X diameter) + 1/2″

The ASTM A193 standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in UNC national coarse thread, diameters above one inch are typically specified 8 threads per inch (tpi).

WINDO METAL manufactures heavy hex bolts from 1/2″ diameter through 2-1/2″ diameter in most ASTM, AASHTO, and SAE specifications. Special tooling can be created to produce nonstandard head dimensions or bolt heads with your company’s name and/or logo. 1. Cutting 2. Heading 3. Threading 4. Hot-Dip Galvanizing

Heavy Hex Bolt Specifications
General heavy hex bolts include ASTM A307 specifications, which covers carbon steel bolts and studs ranging from 1/4” through 4” in diameter. This is the most common heavy hex bolt and includes Grades A, B, and C which denote tensile strength, configuration, and its intended use.

The ASTM A193 specification covers alloy steel and stainless steel bolt materials for high temperature and high pressure applications.

Heavy hex structural bolts are designed for steel-to-steel connections and include ASTM A325 and A490 specifications, which covers bolts from 1/2” up to 1-1/2” in diameter. Since these heavy hex bolts are intended for structural connections, they have shorter thread lengths than standard hex bolts.

As a national base factory and supplier of heavy hex bolt, WINDO Metal Fasteners carries a huge selection of bolt sizes, lengths, materials and finishes, however if you need any assistance fining the heavy hex bolt you need for your application, please contact us today.
