Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
- Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping
- Optimized for 0.025" maximum drilling thickness with precise No. 21 drill bit compatibility
- Secure Phillips drive engagement prevents cam-out during installation while maintaining flush finish
- 82° countersink angle ensures proper seating and clean appearance in sheet metal applications
- Full threading along entire 3/4" length provides maximum holding power and uniform stress distribution
- Environmental compliance assurance with RoHS 3 and REACH regulations for global manufacturing standards
Professional Applications & Engineering Value
These Type A thread forming screws deliver exceptional performance in sheet metal fabrication where traditional fasteners fail. The 18-8 stainless steel composition provides excellent corrosion resistance, eliminating rust concerns in outdoor or humid environments. The thread forming technology displaces material rather than cutting it, creating stronger threads with improved resistance to vibration loosening. The flat head design with 82° countersink sits flush with surfaces, preventing snagging while maintaining structural integrity. Engineered for 0.025" maximum drilling thickness, these screws are perfect for HVAC systems, electronic enclosures, and automotive panels where reliable, long-term fastening is critical.
Specification Summary & Compliance
This No. 10-12 x 3/4" tapping screw features standard Class 2A thread tolerances with 12 threads per inch and 0.19" thread diameter. Manufactured to Type A thread forming specifications with fully threaded right-hand orientation. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial applications. Designed for use with No. 21 drill bits (0.159" diameter) and compatible with standard 82° countersink preparations.
