- Full-length threading ensures maximum grip and vibration resistance across the entire fastener length
- Optimized pan head profile provides a low-profile finish with excellent bearing surface for consistent clamping force
- Precision dimensional accuracy with No. 12 thread diameter and 11 TPI for perfect fit in 3/16" pre-drilled holes
- Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial applications
Professional Applications & Engineering Value
These No. 12 x 1/2" tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for demanding applications. The thread forming design eliminates the need for separate tapping operations, creating precise mating threads that resist vibration loosening and material fatigue. With fully threaded configuration and pointed tip, installation is streamlined while ensuring maximum thread engagement in materials up to 0.025" thickness. The dual Phillips/Slotted drive accommodates various tooling options, enhancing versatility in production environments where different drive systems may be employed.
Specification Summary & Compliance
This tapping screw features precision No. 12 thread diameter (0.216") with 11 threads per inch and right-hand threading conforming to standard industrial specifications. The pan head design with 0.425" diameter and 0.151" height provides optimal clamping surface. Manufactured as Type A/AB thread forming screws for sheet metal applications requiring 3/16" drill preparation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
