Key Features & Benefits at a Glance
- Exceptional strength-to-weight ratio with 160,000 psi tensile and 120,000 psi yield strength for reliable performance in high-stress applications
- Superior corrosion resistance thanks to the A286 stainless steel material and passivated finish, extending service life in harsh environments
- Precise Class 3A thread fit ensures secure, vibration-resistant fastening with minimal risk of loosening
- High-temperature capability of A286 alloy maintains mechanical properties under thermal stress
- Optimized hex socket drive (5/16") allows for high torque application and easy installation in confined spaces
- Full regulatory compliance with RoHS 3 and REACH eliminates supply chain restrictions for global projects
- Coarse UNRC threading enables rapid assembly and reduced cross-threading risks in industrial settings
Professional Applications & Engineering Value
Engineered for demanding applications where failure is not an option, these A286 stainless steel socket head cap screws solve critical fastening challenges in aerospace, heavy machinery, and high-temperature processing equipment. The partially threaded design combined with Class 3A thread fit provides exceptional clamp load distribution while preventing vibration-induced loosening. The passivated finish creates a protective oxide layer that significantly enhances corrosion resistance in chemically aggressive environments. With 160,000 psi tensile strength maintained across temperature extremes, these socket head cap screws deliver reliable performance in structural assemblies, engine components, and precision instrumentation where high-strength fasteners are mission-critical.
Specification Summary & Compliance
Manufactured to precision Class 3A thread tolerances with 3/8"-16 UNRC coarse threading and 1½" minimum thread length. Full compliance with ASME B18.3, NAS1352N6-56, SAE AMS5731, and SAE AMS5737 specifications ensures consistent quality and interchangeability. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for unrestricted global deployment.
