Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel socket head cap screws provide critical corrosion resistance where exposure to chemicals, moisture, or salt spray would compromise ordinary fasteners. The 5/16"-18 UNC coarse threads with Class 3A fit deliver superior engagement in both metals and plastics, while the passivated finish enhances surface durability without compromising dimensional accuracy. The hex socket drive enables high-torque installation in confined spaces common in machinery, marine equipment, and chemical processing systems. These screws maintain structural integrity in applications ranging from precision instruments to heavy-duty equipment, where 70,000 psi tensile strength ensures joint reliability under vibration and dynamic loading conditions.
Specification Summary & Compliance
This socket head cap screw features precision 5/16"-18 UNC coarse threads with Class 3A fit tolerance for superior thread engagement. Manufacturing complies with industry standards for dimensional accuracy, including 1 5/8" length and 1 1/8" minimum thread length. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international regulatory requirements for hazardous substance restrictions and chemical safety in industrial applications.
