• Maximum material penetration with fully threaded 1-1/2" length and pointed tip for secure fastening in up to 0.025" thick materials
• Reliable thread engagement with No. 12 diameter and 11 threads per inch ensuring consistent pull-out resistance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These 18-8 stainless steel oval head tapping screws deliver exceptional value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time while creating stronger thread engagement than cutting alternatives. The A/AB tapping screw type with right-hand threading provides reliable fastening in various metal thicknesses, while the standard oval head profile with 82° countersink angle ensures flush mounting for both functional and aesthetic requirements. Ideal for HVAC systems, electronic enclosures, and industrial equipment where vibration resistance and long-term durability are critical engineering considerations.
