Heavy hex nuts also as known structural bolt, ASTM A325 bolts, machine bolts and so on.
A heavy hex bolt has a larger head diameter and thickness than a regular hex bolt, which makes it stronger and more durable.
Additionally, heavy hex bolts typically have a shorter length than regular hex bolts but are designed to withstand higher levels of stress and tension. This is because the larger head and thicker shank provide a greater area of contact with the material being fastened, which distributes the load more evenly across the bolt.
