S-90315A439 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in harsh industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Secure flush finishing with the standard oval head profile and 82° countersink angle for a smooth, professional appearance in metal assemblies.
• Excellent drive engagement provided by the No. 2 Phillips drive, minimizing cam-out and enabling high-torque installation with standard tools.
• Full threading along the 1-1/2" length ensures maximum grip and uniform stress distribution across the entire fastened joint.
• Reliable material compatibility with a 0.138" diameter and pointed tip, optimized for sheet metal applications up to 0.025" thickness.
• Global regulatory compliance with RoHS 3 and REACH standards, making them suitable for international industrial supply chains.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming technology eliminates the need for separate tapping operations, creating strong, load-bearing threads that resist vibration loosening. The Phillips oval head design provides a flush finish that enhances both safety and aesthetics in assembled products. With full threading along the entire 1-1/2" length, these fasteners distribute clamping force evenly, preventing material deformation in thin-gauge metals. The combination of 18-8 stainless steel material and precise right-hand threads ensures reliable performance in demanding environments including electrical enclosures, HVAC systems, and industrial machinery where corrosion resistant fasteners are essential for long-term durability.

Specification Summary & Compliance
