S-92210A634 3/8"-16 x 2 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 construction and passivated finish, ideal for harsh industrial environments
• Exceptional tensile strength rated at 70,000 psi for reliable performance in heavy-duty applications
• Precise Class 3A thread fit ensures secure fastening and vibration resistance in critical assemblies
• Hex drive design provides superior torque transmission and prevents stripping during installation
• 82° countersink angle allows for flush mounting in standard countersunk holes
• Full threading along the 2 1/2" length enables maximum grip and adjustment flexibility
• Consistent hardness at Rockwell B55 maintains structural integrity under repeated stress

Professional Applications & Engineering Value

These 3/8"-16 UNC flat head screws deliver critical engineering solutions where flush mounting and high-strength fastening are paramount. The 18-8 stainless steel composition with passivated finish provides excellent resistance to oxidation and chemical exposure, making them ideal for marine equipment, food processing machinery, and outdoor structural applications. The coarse thread spacing and Class 3A thread fit ensure rapid installation and reliable performance in vibrating environments, while the hex drive design prevents cam-out during high-torque applications. These fully threaded fasteners maintain consistent 70,000 psi tensile strength across their entire length, providing uniform clamping force in demanding industrial assemblies.
