Professional Applications & Engineering Value
This 316 stainless steel socket head cap screw delivers exceptional corrosion resistance in aggressive settings like chemical processing, marine, and food equipment, where exposure to chlorides and acids is common. The passivated finish enhances surface durability, preventing galling and seizing during high-torque applications. With 1/2"-13 UNC coarse threads and Class 3A fit, it ensures quick assembly and secure clamping in metals and composites, minimizing loosening under vibration. The partially threaded shank allows precise control over engaged length, ideal for machinery, structural frames, and heavy-duty assemblies requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
This fastener features a 1/2"-13 UNC coarse thread with Class 3A precision fit for consistent thread engagement. It adheres to manufacturing standards for dimensional accuracy, including head diameter (3/4"), length (4 1/2"), and drive size (3/8" hex). The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
