Professional Applications & Engineering Value
This socket head cap screw delivers critical engineering solutions for industrial applications requiring high tensile strength and corrosion resistance. The 18-8 stainless steel composition prevents rust and degradation in demanding environments, while the 1"-8 UNC coarse thread with Class 3A fit ensures secure fastening in high-vibration machinery, manufacturing equipment, and structural frameworks. The 3/4" hex drive provides superior torque transmission for efficient installation in confined spaces, reducing assembly time and preventing fastener damage. These partially threaded screws offer precise positioning in automotive, aerospace, and heavy equipment applications where alignment and shear strength are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3 standards with Class 3A thread fit for precision tolerance. Features 1"-8 UNC coarse threads with right-hand direction and minimum 2½" thread length on a 4" overall partially threaded design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Mechanical properties include Rockwell B70 hardness and 70,000 psi tensile strength for reliable performance in inch-system applications.
