S-95639A479 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine and chemical applications.
• Enhanced holding power and vibration resistance with thread forming (Type A/AB) design that creates strong, lasting threads in sheet metal.
• Clean, finished appearance and reduced snagging provided by the standard oval head, which sits flush upon installation.
• Efficient and secure installation with a No. 3 Phillips drive, minimizing cam-out and ensuring reliable torque transfer.
• Full-length threading for maximum grip along the entire 1-1/2" length, ensuring a secure fastening in materials up to 0.025" thick.
• Precision fit and reliable performance with a 0.242" thread diameter and 10 threads per inch, designed for consistent engagement.
• Compliance with major environmental and safety regulations including RoHS 3 and REACH, ensuring suitability for regulated industrial markets.

Professional Applications & Engineering Value

This 316 stainless steel tapping screw is engineered to solve critical challenges in sheet metal assembly, where corrosion and joint failure are primary concerns. The thread forming (Type A/AB) tapping method displaces material to create a zero-clearance fit, eliminating the need for a pre-tapped hole and providing exceptional resistance to loosening under vibration. The fully threaded design and pointed tip ensure easy starting and maximum thread engagement along the entire shank, distributing load evenly for a stronger connection in thin-gauge materials. Combined with the Phillips drive and oval head, these screws offer a reliable, flush-mounting solution for HVAC systems, electronic enclosures, and automotive panels, delivering long-term durability and assembly integrity.
