Key Features & Benefits at a Glance
- Superior sheet metal penetration with pointed tip design and 0.025" maximum drilling thickness for faster, cleaner installations
- Dual-drive versatility with external hex/slotted head providing flexible tool compatibility in tight spaces
- Enhanced holding power through thread forming technology that creates stronger, vibration-resistant connections
- Flanged design eliminates need for separate washers, reducing assembly time and component count
- Full 1-1/4" threading ensures maximum engagement and load distribution across the entire fastener length
- Precision compatibility with standard No. 21 drill bits (0.159" diameter) for consistent, reliable hole preparation
- Environmental compliance assurance with full RoHS 3 and REACH compliance for global industrial applications
Professional Applications & Engineering Value
These No. 10-12 thread forming tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The hex flanged design combined with external hex/slotted drive provides superior torque transmission while the fully threaded configuration ensures maximum pull-out resistance in thin materials. The thread forming action creates precise mating threads without generating chips, eliminating contamination concerns in electrical enclosures, HVAC systems, and automotive panels. With right-hand threading and pointed tip, these screws reduce installation time while maintaining structural integrity in demanding industrial environments where vibration resistance is critical.
Specification Summary & Compliance
This No. 10 tapping screw features a 0.19" thread diameter with 12 threads per inch in right-hand direction, 1-1/4" full threading length, and 0.414" flange diameter. Manufactured to precise dimensional standards for consistent performance in sheet metal applications. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
