Sirius 12.9 Grade Socket Head Cap Screws UNC 1/2 UNC 5" Pack of 50

These Sirius socket head cap screws are engineered for maximum strength and reliability in demanding industrial applications. Made from high-grade alloy steel and heat-treated to a 12.9 hardness level, they offer exceptional tensile strength and resistance to shear forces, making them ideal for securing heavy machinery, automotive assemblies, and structural fixtures. Each screw features a precision-rolled UNC thread for a secure, consistent fit in standard 1/2-inch UNC nuts or tapped holes, and the 5-inch length provides ample grip depth for thick components. The black oxide finish adds a layer of corrosion resistance while reducing glare, and the hex socket drive allows for high torque application without cam-out or stripping, even in tight spaces.
