Description
Hex Head Cap Screws Grade 8 Steel Plain (USA Made) 7/16-20 x 2-1/4 are premium fasteners designed to deliver high clamping force and reliable performance in demanding assemblies. Manufactured in the USA from high-strength steel and finished plain (uncoated), these screws are built for endurance in indoor or protected environments.
Why choose Grade 8 and a plain finish?
Grade 8 steel is quenched and tempered for exceptional strength, delivering superior resistance to shear and torque. The plain finish means there is no plating, making them ideal when you need a clean steel fastener with strong core integrity—though they require proper protection in corrosive environments.
