Socket Head Cap Screws in alloy steel with a durable thermal black oxide finish. This 1 1/2-6 x 4 1/2 screw is designed for heavy-duty assemblies where high strength, precise torque, and a low-profile, flush-headed fastener are essential.

The thermal black oxide coating provides improved wear resistance and a subtle, low-gloss appearance that helps reduce glare and galling in high-load environments. Coupled with strong alloy steel, these screws deliver reliable performance in demanding applications.

Engineered for a secure fit, these socket head cap screws are driven with an Allen key, offering precise torque control and a clean, recessed head profile that remains flush with the surface in many assemblies. Ideal for machinery, automotive, industrial equipment, and precision machinery projects.
