S-95639A331 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or outdoor environments where moisture and chemicals are present.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling needs.
• Optimized for sheet metal up to 0.025" thickness, ensuring secure fastening in thin materials without stripping or damaging the workpiece.
• Clean, finished appearance with an oval head that sits flush when used with standard 82° countersinks, improving aesthetics and safety.
• Reliable drive engagement using a Phillips No. 2 drive, providing good torque transfer and reducing the risk of cam-out during installation.
• Full threading along the 3/4" length offers maximum grip and adjustability in a variety of sheet metal assembly scenarios.
• Compliance with RoHS 3 and REACH regulations ensures the screws are free from hazardous substances, meeting international environmental and safety standards.

Professional Applications & Engineering Value

These 316 stainless steel Phillips oval head tapping screws are precision-engineered for sheet metal applications, where their thread forming (Type A/AB) design eliminates the need for separate tapping operations. This not only speeds up assembly but also produces stronger, more reliable threads by work-hardening the base material. The fully threaded No. 6 shank with 18 TPI ensures excellent pull-out resistance, while the oval head provides a low-profile finish that minimizes snagging and enhances appearance in visible assemblies. Ideal for HVAC systems, electronic enclosures, and automotive panels, these screws deliver long-term corrosion resistance and durability, even in saline or industrial atmospheres.

Specification Summary & Compliance

This No. 6 x 3/4" screw features a 0.138" thread diameter with approximately 18 threads per inch and a standard oval head profile. It is designed for use with a No. 32 drill bit (0.116" diameter) and an 82° countersink angle. Manufactured to common inch-series standards for tapping screws, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
