Professional Applications & Engineering Value

This 3/4"-10 UNC hex head screw delivers critical reliability in demanding industrial applications where failure is not an option. Engineered from 18-8 stainless steel, it provides inherent corrosion resistance, eliminating premature degradation in moist or chemically aggressive environments. The coarse thread design and Class 2A thread fit facilitate faster assembly and superior resistance to loosening under dynamic loads and vibration, a common challenge in machinery and structural steelwork. The partially threaded configuration concentrates the clamping force while the unthreaded shank increases resistance to shear forces, making it an optimal choice for securing heavy plates, construction frames, and high-stress equipment assemblies. Its external hex drive and substantial head size allow for high torque application, ensuring tight, secure connections every time.

Specification Summary & Compliance

This screw conforms to ASME B18.2.1 dimensional and mechanical standards. The UNC coarse thread (3/4"-10) is manufactured to a Class 2A tolerance for consistent fit. It is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to strict environmental regulations for hazardous substances. The material and manufacturing process guarantee the specified 80,000 psi tensile strength and Rockwell B70 hardness.
