- Superior corrosion resistance from the passivated A286 stainless steel material extends service life in harsh environments.
- Precise Class 3A thread fit provides tight tolerances for secure, vibration-resistant assemblies in critical operations.
- High hardness rating (Rockwell C33) enhances wear resistance, maintaining integrity under repetitive loads.
- Full threading design offers uniform load distribution and ease of installation across the entire length.
- Compliance with stringent standards like Fed. Spec. FF-S-86 and SAE AMS5737 guarantees consistency for aerospace and industrial use.
- Hex socket drive allows for high-torque installation with standard tools, minimizing slippage and damage.
Professional Applications & Engineering Value
This A286 stainless steel socket head cap screw is engineered to address demanding industrial challenges, such as vibration loosening and corrosion in aerospace, automotive, and heavy machinery assemblies. The passivated finish provides an added layer of protection against oxidation and chemical exposure, ensuring long-term reliability in extreme conditions. With its Class 3A thread fit and coarse UNRC thread, it delivers superior clamping force and resistance to dynamic stresses, reducing maintenance needs. The high tensile and yield strength (160,000 psi and 120,000 psi, respectively) make it ideal for critical joints where failure is not an option, enhancing overall assembly integrity and safety.
Specification Summary & Compliance
This fastener features a 1/4"-20 thread size with Class 3A fit per UNRC standards, ensuring precise dimensional accuracy. It complies with Fed. Spec. FF-S-86, NAS1352N4-6, and SAE AMS5737 manufacturing specifications, and is verified to meet RoHS 3 and REACH environmental regulations for safe use in global markets.
