S-96209A312 6-32 x 3/8" ASME B18.3 Super-Corrosion-Resistant 316 Stainless Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life.
• Permanent, reliable locking provided by the Nylon Patch, preventing loosening from vibration in temperatures from -70° to 250° F.
• High-strength performance with a 70,000 psi tensile strength and Rockwell B70 hardness for demanding applications.
• Precise and secure fastening ensured by the Class 3A thread fit, minimizing the risk of cross-threading and ensuring consistent clamp load.
• Easy installation and high torque capability with the standard hex socket (7/64" drive) and socket head profile.
• Versatile coarse (UNC) threading for quicker assembly and better performance in softer materials or where debris is present.
• Full regulatory compliance with ASME B18.3, RoHS 3, and REACH, ensuring quality and environmental safety for global supply chains.

Professional Applications & Engineering Value

This 316 Stainless Steel Socket Head Cap Screw is engineered to solve critical fastening challenges in industrial and mechanical assemblies. The Nylon Patch thread locker is permanently applied, creating a prevailing torque that resists vibration-induced loosening, making it an excellent choice for machinery, automotive sub-assemblies, and electronic enclosures subject to dynamic loads. The UNC coarse thread and Class 3A fit provide superior engagement and durability, reducing installation time and the risk of thread stripping. Manufactured from corrosion-resistant 316 stainless steel, it delivers long-term reliability in corrosive environments, from chemical processing equipment to marine applications. The combination of high tensile strength and the secure hex drive ensures that these screws can be tightened to precise torque specifications, maintaining joint integrity under stress.
