- Precise Class 3A thread fit provides secure, vibration-resistant connections, minimizing loosening in dynamic assemblies.
- High hardness (Rockwell C33) offers excellent wear resistance, maintaining thread integrity through repeated use.
- Hex socket drive design allows for high torque application and easy installation in confined spaces.
- Compliance with major standards including ASME B18.3 and NAS1352N6-80 ensures consistent quality and interchangeability.
- Partially threaded shank provides optimal grip length for precise clamping without unnecessary thread engagement.
Professional Applications & Engineering Value
This high-strength socket head cap screw addresses critical engineering challenges in demanding industries such as aerospace, automotive, and heavy machinery. The A286 stainless steel composition delivers outstanding creep resistance at elevated temperatures, while the passivated finish significantly enhances corrosion protection against chemicals and moisture. The Class 3A thread fit with UNRC coarse threads ensures rapid assembly and superior vibration resistance, crucial for equipment subjected to dynamic loads. The 5/16" hex drive accommodates high torque requirements, and the partially threaded design concentrates clamping force exactly where needed. These features make it ideal for critical joints in engine components, structural frames, and precision equipment where reliability and durability are paramount.
Specification Summary & Compliance
This socket head cap screw features precision 3/8"-16 UNRC coarse threads with Class 3A fit for tight tolerances. It meets ASME B18.3, NAS1352N6-80, and SAE AMS5731/5737 specifications, ensuring consistent manufacturing quality. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial applications.
