Earnest’s line of Heavy Hex Bolts, per ASTM A307 Grade B are designed to ensure the clamp loads developed in assembly are distributed over a larger area than the standard hex heads. They also provide a larger wrenching area to resist rounding out of the head. A307 Grade B Heavy Hex Bolts are commonly used in applications where the bolt strength needs to be controlled — meaning the bolt will break before equipment is destroyed.
