S-95639A488 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or humid industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling.
• Clean, finished appearance provided by the standard oval head that sits flush with the material surface.
• Secure, cam-out resistant driving with the No. 3 Phillips drive, ensuring reliable torque transfer and reduced tool slippage.
• Optimized for 0.025" sheet metal with a pointed tip and 82° countersink angle for precise, flush seating and maximum holding power.
• Full threading along the 2-1/2" length offers consistent grip and adjustable fastening depth for versatile applications.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industrial standards for hazardous substances.

Professional Applications & Engineering Value

These 316 Stainless Steel Phillips Oval Head Tapping Screws are engineered to solve critical challenges in sheet metal assembly. The thread forming (Type A/AB) design displaces material to create robust, strip-resistant threads, eliminating the need for a separate tapping operation and speeding up production lines. The fully threaded No. 14 screw with a 0.242" diameter and 10 TPI ensures high pull-out strength and vibration resistance in thin-gauge materials. The oval head with an 82° countersink provides a smooth, low-profile finish that enhances product aesthetics while preventing snagging. Made from 316 stainless steel, these screws deliver exceptional performance in corrosive environments, such as outdoor enclosures, marine hardware, and chemical processing equipment, ensuring long-term reliability and reduced maintenance.

Specification Summary & Compliance

This tapping screw features a right-hand thread with a diameter of 0.242" and approximately 10 threads per inch (TPI), conforming to standard inch-series tolerances. The screw is fully threaded with a thread forming (Type A/AB) tapping method and a pointed tip for easy starting. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances and safe for industrial use globally.
