HEX HEAD BOLTS
Characterized by a six-sided hexagon-shaped head, hex head bolts are versatile threaded fasteners used in a range of applications throughout many industries including chemical processing, semi-conductors, power generation, pulp and paper mills, water systems and more.
Because of their shape, hex head bolts are ideal for use in small spaces since they're easier to grip and remove than other types of bolts.
Available as either partially or fully threaded, Hastelloy screws China Inc. stocks hex head bolts in a variety of materials and lengths starting at 1/4" in diameter.
