S-95639A381 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel material, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Secure Phillips No. 2 drive provides reliable torque transfer and minimizes cam-out during high-speed assembly operations.
• Full threading along the 2" length ensures maximum grip and holding power across the entire material thickness.
• Standard oval head with 82° countersink offers a flush, professional finish that eliminates snagging and improves safety.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets global industrial standards.
• Optimized for use with No. 29 drill bit (0.136" diameter) for precise pilot holes, ensuring accurate alignment and reduced material stress.

Professional Applications & Engineering Value

These 316 stainless steel oval head tapping screws are engineered specifically for sheet metal applications, where corrosion resistance and structural integrity are critical. The thread forming (Type A/AB) technology displaces material rather than cutting it, resulting in stronger thread engagement and higher resistance to vibration loosening. This is particularly valuable in automotive, HVAC, and electronic enclosure assemblies, where fully threaded fasteners provide consistent clamping force. The right-hand threaded design with a pointed tip ensures quick starts and smooth penetration into metals up to 0.025" thick, reducing the risk of cross-threading and improving production line efficiency.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 8 screw size and 2" length, featuring a Class 2A thread fit for reliable assembly. The oval head profile is designed for standard countersunk holes with an 82° angle. Manufacturing and material compliance include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring they are free from hazardous substances and suitable for regulated industrial markets.
