Heavy Hex Bolts Manufacturer & Suppliers in Ghana & Africa

7 Eleven Baseline Bolts is a heavy hex bolts manufacturer and suppliers in Ghana, providing high-quality heavy hex bolts for structural steel, construction, engineering, machinery, infrastructure, and industrial applications across Ghana and Africa.

How we deliver:

Certain ASTM specifications require a hex head that is larger than a standard finished hex head. These include A320, A193, and A307 Grade B. While A325 and A490 bolts also require a heavy hex head, it is important to refer specifically to structural bolt standards when reviewing their dimensional requirements, as these bolts are designed with shorter thread lengths compared to standard heavy hex bolts.

Applications

Heavy hex bolts are used across a wide range of applications, including fastening wood, steel, and various other construction materials. They are commonly employed in major projects such as bridges, buildings, docks, and highway structures. In some cases, heavy hex bolts are manufactured with forged heads and are typically used as headed anchor bolts due to their strength and load-bearing capability.

Manufacturing

7 Eleven Baseline Bolts manufactures superior-quality heavy hex bolts in diameters ranging from 1/2″ to 2-1/2″, meeting most ASTM, SAE, and AASHTO specifications. We also offer custom manufacturing solutions, including special tooling to produce non-standard bolt heads and head dimensions with the client’s preferred logo and/or name for distinctive brand identification.

Stock

Standard Thread Lengths

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