Cold forged yellow zinc Trivalent chromium A325 structural heavy hex bolt
Heavy hex bolts are required based on a number of different ASTM bolt specifications. In the chemical and petroleum industries, the A193 specification calls for heavy hex bolts and nuts in high heat conditions. The A320 standard covers extremely low temperature conditions and requires the use of heavy hex bolts. Also in ASTM specifications the A307 standard dictates that heavy hex bolts are required in situations where the flanged joints within piping systems are made with cast iron flanges.
As well as the standards above, the A490 and A325 specifications call for heavy hex bolts, but with a shorter thread than the others.
