- Enhanced holding power with fully threaded shank and 82° countersink angle for maximum grip in sheet metal applications
- Optimized for 0.025" maximum drilling thickness using standard No. 21 drill bits for precise, secure fastening
- Reliable drive engagement with No. 2 Phillips head ensuring consistent torque transfer and reduced cam-out
- Clean, finished appearance thanks to oval head design that sits flush with material surfaces
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe, sustainable manufacturing
Professional Applications & Engineering Value
These No. 10 x 7/8" stainless steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread forming capability eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The 18-8 stainless steel material provides excellent corrosion resistance, making these oval head Phillips screws suitable for outdoor equipment, electrical enclosures, and HVAC systems where environmental exposure is a concern. The combination of fully threaded design and 82° countersink angle ensures maximum material engagement and holding power in thin gauge metals up to 0.025" thickness, preventing pull-out failures in demanding industrial applications.
Specification Summary & Compliance
These A/AB type tapping screws feature precision 0.19" thread diameter with 12 threads per inch in right-hand orientation, manufactured to industry standards for consistent performance. The oval head profile with standard dimensions (0.362" head diameter, 0.176" head height) provides optimal countersinking capability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for global industrial applications.
