Professional Applications & Engineering Value
This 7/8"-9 UNC hex head screw delivers critical engineering advantages where corrosion resistance and structural integrity are paramount. Manufactured from 18-8 Stainless Steel with 80,000 PSI tensile strength, it withstands extreme mechanical stresses in construction, heavy machinery, and marine applications. The coarse thread spacing and Class 2A fit prevent galling during high-torque installations while maintaining vibration resistance. The external hex drive accommodates standard tools for efficient maintenance in confined spaces. Fully threaded for maximum grip length, this industrial-grade fastener solves common challenges of joint failure, material degradation, and compliance requirements in demanding B2B environments.
Specification Summary & Compliance
This hex head screw maintains Class 2A thread fit tolerance per UNC standards with 7/8"-9 coarse threading and right-hand direction. Manufacturing conforms to inch system dimensions: 1-1/4" length, 1-5/16" head width, and 35/64" head height. Material properties include Rockwell B70 hardness and full threading throughout the shank. The product is verified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety regulations for industrial components.
