S-92185A506 1/4"-20 x 1 3/8" Super-Corrosion-Resistant 316 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 316 stainless steel construction, ideal for harsh chemical and marine environments
• Exceptional thread reliability with Class 3A fit, ensuring precise engagement and reduced risk of cross-threading in high-vibration applications
• High mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for demanding load-bearing assemblies
• Optimized drive performance featuring a standard hex socket and 3/16" drive for secure tool engagement and high torque transmission
• Enhanced durability from the passivated finish, which increases surface hardness and provides added protection against oxidation
• Versatile fastening solution with a 1/4"-20 UNC coarse thread and 1" minimum thread length for quick assembly and strong holding power
• Compliance with global standards including RoHS 3 and REACH, making them suitable for regulated industrial and export markets

Professional Applications & Engineering Value

Engineered for reliability in demanding conditions, these 316 stainless steel socket head cap screws solve critical fastening challenges in industries like chemical processing, marine, and food equipment. The Class 3A UNC coarse thread provides superior resistance to loosening under vibration, while the passivated finish enhances the innate corrosion resistance of 316 stainless steel, preventing failure in humid or corrosive settings. With a partially threaded design and high tensile strength, they are ideal for applications requiring precise clamp load and repeated disassembly, such as machinery frames, pumps, and precision instruments. Their hex socket drive allows for compact installation in confined spaces, ensuring efficient maintenance and assembly operations.
