Key Features & Benefits at a Glance
- Superior holding power in sheet metal with 11 threads per inch and 0.216" thread diameter for reliable, vibration-resistant fastening
- Easy installation and reduced assembly time thanks to the external hex/slotted drive and pointed tip for quick penetration
- Enhanced load distribution and stability from the 0.432" flange diameter, minimizing surface damage and loosening
- Durable thread forming design that creates strong, precise threads in pre-drilled holes without chip removal
- Corrosion-resistant and industry-compliant construction meeting RoHS 3 and REACH standards for long-term reliability
- Full 3" threading ensures maximum grip length for thick sheet metal applications
- Wide compatibility with standard 3/16" drill bits and up to 0.025" maximum drilling thickness
Professional Applications & Engineering Value
These No. 12-11 thread forming tapping screws are engineered to address common challenges in sheet metal assembly, where vibration resistance and pull-out strength are critical. The thread forming design eliminates chips during installation, reducing contamination risks in sensitive environments like HVAC systems, electronic enclosures, and automotive panels. With a hex head and external hex/slotted drive, they allow for high-torque application using standard tools, speeding up production lines. The fully threaded shank and pointed tip ensure quick starts and consistent engagement, while the flanged design distributes clamping force evenly, preventing sheet deformation. Ideal for industrial settings requiring RoHS and REACH compliance, these screws deliver lasting performance in corrosive or regulated conditions.
Specification Summary & Compliance
This product features a No. 12 screw size with 0.216" thread diameter and 11 TPI in a right-hand thread direction, fully threaded along the 3" length. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met. The screw is designed for use with a 3/16" drill bit (0.1875" diameter) and supports a maximum drilling thickness of 0.025", making it suitable for precise sheet metal applications.
