• Full-length threading for maximum grip strength and consistent fastening performance across the entire 4" length
• Precision drilling compatibility with 5.5mm (0.2165") drill bits, ensuring accurate hole preparation and secure fastening
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time while creating stronger, more reliable threads that resist vibration loosening. The Type A thread design with 10 TPI provides optimal thread engagement in materials up to 0.025" thickness, making these Phillips flat head screws ideal for HVAC systems, electrical enclosures, and industrial equipment manufacturing. The combination of fully threaded construction and pointed tip ensures quick starting and smooth installation, while the 82° countersink angle allows for flush mounting in precision sheet metal work.
