  • Streamlined installation with pointed tip and fully threaded design for faster, easier driving without pre-tapping
  • Optimized compatibility with standard No. 21 drill bits (0.159") for precise hole preparation and maximum material thickness of 0.025"
  • Secure fastening performance with No. 10-12 thread configuration providing excellent holding power in thin materials
  • Clean, professional appearance from rounded button head design that sits flush with mounted surfaces
  • Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

This No. 10 thread forming tapping screw delivers exceptional engineering value in sheet metal applications where security and reliability are paramount. The tamper-resistant hex drive (5/32") provides vandal-resistant fastening for enclosures, electrical boxes, and access panels while maintaining installation efficiency. The A/AB thread forming design creates precise mating threads in parent material, eliminating the need for separate tapping operations and reducing assembly time. With fully threaded construction and pointed tip, these screws penetrate smoothly while minimizing material displacement, preventing cracking in thin-gauge metals. The rounded button head profile offers a finished appearance while the 12 threads per inch configuration ensures optimal load distribution across the entire 1" length, making it ideal for HVAC systems, electronic enclosures, and industrial machinery where vibration resistance is critical.

Specification Summary & Compliance

This inch-system fastener features precision Class 2A thread tolerances with 0.19" thread diameter and 12 TPI configuration. Manufactured to A/AB tapping screw standards for thread forming applications, the screw demonstrates compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The tamper-resistant hex drive requires specialized 5/32" tools for installation, while the rounded button head (0.361" diameter, 0.101" height) provides consistent seating in prepared No. 21 drill bit holes (0.159" diameter).
