Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel socket head cap screws deliver exceptional performance where corrosion resistance and mechanical reliability are paramount. The 1/2"-13 UNC coarse thread configuration provides rapid assembly in thick materials and high-vibration applications, while the Class 3A thread fit ensures precise tolerances for critical joint integrity. The passivated finish significantly enhances the natural corrosion resistance of 316 stainless steel, making these fasteners ideal for chemical processing equipment, marine hardware, food processing machinery, and pharmaceutical applications where exposure to aggressive media is common. The partially threaded design offers flexibility in applications requiring both clamping force and alignment functions, while the hex socket drive enables high-torque installation in confined spaces.

Specification Summary & Compliance

This socket head cap screw features precision Class 3A thread fit according to UNC standards with 1/2"-13 thread size and coarse thread spacing. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fastener maintains dimensional accuracy with 5 1/2" length, 3/4" head diameter, and 1/2" head height, manufactured from 316 stainless steel with passivated finish for enhanced corrosion protection.
