Hex head bolts have hexagonal heads for firm wrench tightening. Also called engineer's bolts, they securely fasten infrastructure that requires high-tensile strength. These bolts are frequently used in confined spaces because wrenches can access the hex heads from all angles.

Choosing the right hex bolts can significantly impact the efficiency and reliability of mechanical systems. Professionals, including metalworkers, maintenance technicians, and mechanics, require precise, durable, and application-specific fasteners to ensure optimal performance.

Hex Bolts are commonly called cap screws or machine bolts. Hex bolts are available in grade 2 (also 307A), grade 5, and grade 8. They can be zinc plated or hot dipped galvanized.
