What is a heavy hex head bolt?
Heavy Hex Bolts. Heavy Hex Bolts 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.
Advantages / Features:
Our company has purchased steel from several large steel groups , such as Hangzhou Steel Mill, Shanghai Bashan Steel Mill, Beijing Shrugging Steel Mill whose steel have good mechanical properties and stability of chemical component. it keep the bolt to be of high strength. 1/2-13 X 1 ASTM A193 GR B7 Heavy Hex Bolt Black Oxide
