S-93195A221 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread-forming installation with Type B design creates strong, permanent threads in sheet metal without pre-tapped holes.
• Secure flush mounting thanks to the standard 82° flat head profile and Phillips No. 2 drive, preventing snagging and providing a clean finish.
• Excellent pull-out resistance from the fully threaded No. 6-20 configuration, ensuring a reliable, vibration-resistant hold in materials.
• Simplified assembly process with a blunt tip and right-hand thread, allowing for straightforward driving and reduced risk of cross-threading.
• Regulatory peace of mind with full compliance to RoHS 3 and REACH standards, meeting stringent international environmental and safety regulations.
• Optimized for sheet metal with a recommended No. 32 drill bit (0.116" diameter), ensuring precise hole preparation and maximum thread engagement.

Professional Applications & Engineering Value

This 18-8 Stainless Steel Phillips Flat Head Tapping Screw is engineered to solve common fastening challenges in sheet metal applications, such as HVAC systems, electronic enclosures, and automotive panels. Its thread forming Type B design displaces material to create robust, high-strength threads without the need for tapping, reducing assembly time and tooling costs. The fully threaded shank and 82° countersink angle provide superior clamping force and a flush surface finish, critical for aerodynamic and aesthetic requirements. Made from durable stainless steel, it resists rust and corrosion in demanding environments, while the Phillips drive ensures common tool compatibility. This screw delivers reliable performance where vibration resistance and long-term integrity are paramount.

Specification Summary & Compliance
