Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
• Optimal material compatibility with a standard 82° countersink angle for a clean, flush finish in sheet metal assemblies.
• Reliable drive performance from the Phillips No. 2 drive, providing good torque transfer and reducing cam-out risk.
• Full-length threading ensures maximum grip and holding power along the entire 1" length for secure fastening.
• Precision fit with recommended No. 32 drill bit (0.116" diameter) for proper hole sizing and thread engagement.
• Compliance assurance with RoHS 3 and REACH regulations, guaranteeing safety and environmental responsibility for industrial use.

Professional Applications & Engineering Value

These 316 stainless steel Phillips flat head tapping screws are engineered to solve critical challenges in sheet metal fabrication and assembly. The thread forming (A/AB type) design displaces material to create robust internal threads, eliminating the need for separate tapping operations and reducing labor costs. This is particularly valuable in high-volume production environments. The fully threaded No. 6 screw with a 0.138" thread diameter and 18 TPI provides excellent pull-out resistance, ensuring components remain securely fastened under vibration and load. The flat head with its standard profile sits flush, preventing snagging and contributing to a professional finish. Manufactured from 316 stainless steel, these screws offer exceptional resistance to corrosion from chemicals, saltwater, and industrial atmospheres, making them a reliable, long-term industrial fastener solution for HVAC, electronics enclosures, and marine applications where durability is non-negotiable.
