Although the head dimensions for structural bolts are the same as any heavy hex headed fastener per asme b18 2 6 2011 a325 heavy hex bolts have a shorter thread length than most other construction fastener grades.
Because of our manufacturing expertise haydon bolts is able to custom manufacture structural bolts to from 1 2 to 4 diameter in a variety of lengths and grades as a result we are able to shorten lead times for our customers.
These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.
Length is measured from under the head.
Partially threaded screws come with precise threaded and unthreaded portions allowing you to place only the.
