We are leading Manufacturers & Supplier of Square Bolts in Nickel 200/201, Monel 400, Inconel 600/625, Incoloy 800 ,800H & 800HT, Hastelloy C22/Hastelloy C276, Alloy 904 L/Alloy 20, Ti Grade 1/2/3/4/5/7. Square head machine bolts were the industry standard prior to hex bolts gaining prominence. Square bolts are now most commonly used for aesthetic purposes to provide a rustic look in a new structure or to match existing fasteners in an older structure. Square lag screws are also used for these purposes.
Cross arm or machine bolts are commonly supplied for the utility industry and included an added cone point.
Standard Thread Lengths :
- Bolt lengths < 6": Thread length = (2 X diameter) + 1/4"
- Bolt lengths > 6": Thread length = (2 X diameter) + 1/2"

We are leading Manufacturers & Suppliers of heavy hex bolts in Nickel 200/201, Monel 400, Inconel 600/625, Incoloy 800 ,800H & 800HT, Hastelloy C22/Hastelloy C276, Alloy 904 L/Alloy 20, Ti Grade 1/2/3/4/5/7. There are several ASTM specifications require a hex head that is larger than a standard(finished) hex head. These specifications include: A193, A320 and A307B. AlthoughA325 and A490 bolts also require a heavy hex head, please refer to Structural Boltsfor dimensional specifications, since these bolts have shorter thread lengths than standard heavy hex bolts.
Applications :
It can be used for many different applications that include fastening wood, steel, and other construction materials. Heavy hex bolts with forged heads are also commonly used as headed anchor bolts.
Standard Thread Lengths:
- Bolt lengths < 6": Thread length = (2 X diameter) + 1/4"
Bolt lengths > 6": Thread length = (2 X diameter) + 1/2"

We are leading Manufacturers & Suppliers Headed anchor bolts in Nickel 200/201, Monel 400, Inconel 600/625, Incoloy 800 ,800H & 800HT, Hastelloy C22/Hastelloy C276, Alloy 904 L/Alloy 20, Ti Grade 1/2/3/4/5/7. These are different from bent anchor bolts or anchor rods, because the non-threaded end has a forged hex, heavy hex or square head. The headed end is embedded into concrete foundations to secure structural steel columns, light poles, bridge rail, and substation structures. Available specifications include, but are not limited to, ASTM F1554, A449, and A307.
