S-92210A637 3/8"-16 x 3 1/2" ASME B18.3 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and passivated finish, ideal for harsh industrial environments
• Exceptional tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration
• Precise Class 3A thread fit provides secure, tight fastening with reduced risk of cross-threading
• Full threading along the 3 1/2" length offers maximum grip and uniform stress distribution
• 82° countersink angle with standard flat head profile enables flush mounting for clean, aerodynamic surfaces
• Hex drive (7/32") design allows for high-torque installation with standard tools, minimizing slippage
• Compliance with ASME B18.3, RoHS 3, and REACH guarantees quality, safety, and environmental standards

Professional Applications & Engineering Value

These 3/8"-16 UNC flat head screws are engineered to address critical challenges in industrial assembly and heavy machinery. The 18-8 stainless steel construction, enhanced by a passivated finish, resists oxidation and chemical exposure, extending service life in demanding settings like manufacturing plants and outdoor equipment. The coarse UNC threads and Class 3A fit ensure rapid, secure installation with minimal galling, while the hex drive accommodates high torque for robust connections. Ideal for applications requiring flush mounting—such as conveyor systems or structural frameworks—the 82° countersink and fully threaded design distribute load evenly, reducing stress concentrations and preventing loosening under dynamic forces.
