S-95639A312 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to premium 316 stainless steel construction, ideal for outdoor or chemical-exposed applications.
• Efficient thread forming creates strong, permanent threads in sheet metal up to 0.025" thick, reducing the risk of stripping and improving joint integrity.
• Clean, finished appearance with a standard oval head that sits flush against surfaces, providing a professional look while minimizing snagging.
• Reliable driving performance with a No. 1 Phillips drive, ensuring secure bit engagement and reducing cam-out during installation.
• Full threading along the 1" length offers maximum grip and adjustability in sheet metal assemblies, enhancing fastening security.
• Compliance with strict environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global industrial supply chains.
• Precision sizing with No. 4-24 thread and pointed tip for easy starting and consistent performance in pre-drilled holes (No. 44 drill bit recommended).

Professional Applications & Engineering Value

This 316 stainless steel Phillips oval head tapping screw is engineered to address common challenges in sheet metal fabrication, where corrosion and material fatigue are primary concerns. The thread forming (Type A/AB) design displaces material rather than cutting it, creating stronger threads with improved resistance to vibration loosening. This is critical in industrial applications such as HVAC systems, electronic enclosures, and automotive panels, where corrosion-resistant fasteners must maintain clamp load under stress. The combination of a fully threaded shank and 82° countersink angle ensures a tight, flush fit, reducing gaps where moisture or contaminants could accumulate. By specifying this RoHS and REACH compliant screw, engineers achieve long-term reliability in demanding environments without compromising regulatory adherence.

Specification Summary & Compliance

This screw conforms to standard inch measurements with a No. 4-24 thread (24 TPI) and Class 2A thread fit for consistent engagement. The thread forming tapping method follows Type A/AB specifications, suitable for ductile materials like sheet metal. It is manufactured from 316 stainless steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use worldwide.
