Professional Applications & Engineering Value

These Type A thread forming screws deliver exceptional value in sheet metal fabrication and industrial assembly applications. The 18-8 stainless steel composition provides reliable corrosion resistance while maintaining structural integrity in demanding environments. The thread forming design eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The flat head with 82° countersink ensures flush mounting for safety and aesthetic requirements, while the No. 2 Phillips drive offers familiar, efficient installation. These tapping screws are engineered to handle maximum drilling thickness of 0.025" with recommended No. 21 drill bit preparation, making them ideal for HVAC systems, electronic enclosures, and automotive components where reliable fastening is critical.
