Hex Head Cap Screws

Hex head cap screws feature a solid six-sided hexagon-shaped head which allows for greater torque than traditional screws. These common threaded fasteners do not require a nut for fastening and are designed to secure objects within or against other objects for a secure, non-loosening hold.

Hex head cap screws are versatile and can be used in a variety of applications. Due to their strength and durability, these fasteners are commonly used in construction, machine parts and maintenance repairs.

Available as either partially or fully threaded, Nickel Systems stocks hex head cap screws in a variety of materials and lengths starting at 1/4″ in diameter.
