Professional Applications & Engineering Value

These 10-32 UNF socket head cap screws deliver critical performance advantages in precision engineering applications where fine thread fasteners are essential. The zinc-plated alloy steel construction provides superior corrosion protection while maintaining the 170,000 psi tensile strength required for high-stress assemblies. The Class 3A thread fit ensures precise engagement in tapped holes, minimizing vibration-induced loosening in machinery, automotive components, and industrial equipment. The hex socket drive allows for high torque application in confined spaces, making these fully threaded screws ideal for applications requiring consistent clamping force along the entire fastener length. Engineered to ASTM A574 standards, these screws provide reliable performance in critical applications where fastener failure is not an option.

Specification Summary & Compliance

This socket head cap screw features precision 10-32 UNF fine threads with Class 3A fit for superior thread engagement and dimensional accuracy. Manufactured to ASTM A574 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fastener maintains tight dimensional tolerances throughout its 1" length with fully threaded design and right-hand thread direction for standard industrial applications.
