Professional Applications & Engineering Value
These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming technology eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The Phillips pan head design provides a low-profile fastening solution with excellent driver engagement, making these No. 12 screws ideal for HVAC systems, electronic enclosures, and automotive panels where corrosion resistance and structural integrity are critical. The combination of 0.216" thread diameter and 3-1/2" length offers optimal penetration for joining multiple sheet metal layers up to the specified maximum thickness.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread tolerances and right-hand threading throughout the entire 3-1/2" length. These thread forming screws conform to A/AB type specifications with 11 TPI thread pitch and 0.425" head diameter pan head profile. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global manufacturing applications requiring restricted substance control.
