S-92185A886 7/8"-9 x 3" Super-Corrosion-Resistant 316 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction and passivated finish, ideal for harsh environments and extended service life
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration in demanding applications
• Precision Class 3A thread fit provides consistent engagement and reduces the risk of cross-threading during assembly
• 3/4" hex drive and standard socket head allow for high torque application and secure fastening in confined spaces
• Coarse UNC threads enable quicker installation and are less prone to clogging in dirty or debris-filled conditions
• Partially threaded design offers optimal clamping force distribution and prevents loosening in dynamic applications
• Rockwell B70 hardness provides excellent wear resistance and maintains thread integrity through repeated use

Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw delivers exceptional engineering value in corrosive and high-stress environments where fastener failure is not an option. The combination of 70,000 psi tensile strength and Class 3A UNC threads ensures reliable performance in heavy machinery, marine equipment, and chemical processing applications where vibration resistance and precise fit are critical. The passivated finish significantly enhances corrosion resistance beyond standard stainless steel, making it suitable for offshore platforms, food processing equipment, and pharmaceutical manufacturing where sanitation and durability are paramount. The 3/4" hex drive accommodates standard industrial tools for efficient maintenance and assembly operations.
