Heavy hex bolts are hex head bolts with heavy profile. The hex and the thickness of the bolt head are considerable larger then standard hex head bolts. Heavy hex head bolts are available in both metric and inch sizes with UN, UNC, UNF, UNEF and ISO metric threads. Heavy hex bolts are produced in high tensile grades, stainless steel and majority of ASTM bolting specifications.
Metric : M6 to M100
Inch/Imperial : 3/8" to 4"
Threads : UN, UNC, UNF, UNEF, ISO Metric and BSW.
