S-95639A362 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or chemical-exposed industrial environments.
• Enhanced holding power and vibration resistance through thread forming technology, which creates strong, secure threads in sheet metal without pre-tapping.
• Clean, finished appearance and reduced snagging due to the undercut oval head design, which sits flush with the material surface.
• Efficient and secure drive engagement with a No. 2 Phillips drive, preventing cam-out and allowing for high-torque installation.
• Optimized for thin sheet metal applications with a maximum drilling thickness of 0.025", ensuring reliable performance in specified materials.
• Full thread engagement along the 3/8" length provides consistent clamping force and pull-out resistance across the entire fastener.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global industrial supply chains.

Professional Applications & Engineering Value

This 316 stainless steel Phillips oval head tapping screw is engineered to solve critical challenges in sheet metal fabrication and assembly. Its thread forming (Type A/AB) design displaces material to create strong, permanent internal threads, eliminating the need for a separate tapping operation and reducing assembly time and cost. The fully threaded shank and 15 TPI (Threads Per Inch) ensure maximum thread contact, providing exceptional resistance to vibration loosening and pull-out forces. The undercut oval head with an 82° countersink angle is specifically designed to sit flush, preventing protrusion and offering a smooth, professional finish. Made from high-grade 316 stainless steel, it delivers unmatched corrosion resistance, making it the preferred choice for demanding applications in marine, chemical processing, and outdoor equipment where durability is non-negotiable.
