S-95639A325 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial and marine environments
• Strong, permanent thread formation in sheet metal up to 0.025" thickness without requiring pre-tapped holes
• Secure, flush-mount installation provided by the standard oval head profile and Phillips No. 2 drive
• Excellent vibration resistance through thread forming technology that creates zero-clearance mating threads
• Precision installation guidance with recommended No. 32 drill bit (0.116" diameter) for optimal performance
• Full environmental compliance meeting RoHS 3 and REACH standards for regulated applications
• Consistent thread engagement with fully threaded shank and 18 threads per inch for reliable fastening

Professional Applications & Engineering Value

These 316 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and assembly applications where corrosion resistance and thread integrity are critical. The thread forming design eliminates the need for separate tapping operations while creating stronger, more durable threads than conventional cutting screws. The Phillips oval head provides both aesthetic appeal and functional benefits, sitting flush with surfaces while the No. 2 drive ensures efficient installation. Engineered specifically for sheet metal up to 0.025" thickness, these A/AB type screws prevent material distortion and provide reliable performance in HVAC systems, electronic enclosures, marine equipment, and industrial machinery where exposure to moisture, chemicals, and temperature variations demands superior corrosion resistance.
