Professional Applications & Engineering Value

These thread forming tapping screws are engineered specifically for sheet metal applications where reliable fastening and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent durability against environmental factors, while the pan head design with one-way drive offers tamper-resistant security in industrial settings. The thread forming technology eliminates the need for separate tapping operations, creating strong, strip-resistant threads that maintain integrity under vibration and load stress. Ideal for HVAC systems, electrical enclosures, and metal fabrication projects, these screws deliver consistent performance with their fully threaded design and pointed tip that ensures quick penetration and proper alignment in pre-drilled holes.

Specification Summary & Compliance

These No. 10-12 thread forming tapping screws feature a 3/4" length with fully threaded configuration and 0.19" thread diameter. Manufactured to precise dimensional standards with right-hand threading and 12 threads per inch. The screws are designed for use with No. 21 drill bits (0.159" diameter) in sheet metal applications with maximum drilling thickness of 0.025". Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international standards for hazardous substance restrictions.
