SS Heavy Hexagon Head Bolt – ASTM A 193 B8M Dia M42

Hex bolts are a very common choice when it comes to building and repair, often called hexagon screw head bolts, hex cap bolts, hex cap screws, or machine bolts. Hexagon screw head bolts come in a wide range of diameters and sizes. The best way to pick the right hex bolt is to find the material which best suits your needs. Hex bolts are available with standard threading or with full threading, depending on the length of the bolt.
