• Superior tensile strength of 70,000 psi ensures reliable, high-strength fastening for demanding mechanical assemblies.
• Precise Class 3A thread fit provides tighter tolerances for secure engagement and reduced risk of loosening under vibration.
• Durable Rockwell B70 hardness offers excellent wear resistance and maintains thread integrity through repeated use.
• Hex socket drive design allows for high-torque installation in confined spaces, preventing cam-out and head stripping.
• Full compliance with ASME B18.3 guarantees dimensional consistency and interchangeability with other standard components.
• RoHS 3 and REACH compliance ensures the screw meets strict environmental and safety regulations for global supply chains.

Professional Applications & Engineering Value

This 8-32 UNC thread socket head cap screw is engineered to solve critical fastening challenges in precision machinery, automation systems, and heavy-duty equipment. The 18-8 Stainless Steel material provides inherent resistance to rust and oxidation, making it suitable for applications exposed to moisture, chemicals, or outdoor elements. The coarse UNC thread and Class 3A fit enable quick assembly with enhanced holding power, reducing the risk of cross-threading in high-vibration environments. Its hex drive and compact socket head profile are ideal for tight-clearance installations where wrenches cannot fit, ensuring secure fastening in aerospace, automotive, and electronic enclosures. By combining high tensile strength with rigorous standard compliance, this screw delivers long-term reliability and reduces maintenance cycles in industrial settings.

Specification Summary & Compliance

This socket head cap screw features an 8-32 UNC coarse thread with a Class 3A thread fit for precision engagement. It is manufactured to ASME B18.3 specifications, ensuring dimensional accuracy for the 1/2" length, 9/64" hex drive, and other critical measurements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and safe for use in regulated markets.
