Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
- Superior thread-forming capability that creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
- Optimized Phillips No. 3 drive provides secure tool engagement and reduces cam-out risk during high-torque applications.
- Fully threaded design delivers maximum grip and uniform clamping force along the entire 2-1/2" length.
- Precision 11 TPI threading ensures consistent engagement and reliable performance in sheet metal assemblies.
- Standard pan head profile offers a low-profile finish with excellent bearing surface for secure fastening.
- Environmental compliance with RoHS 3 and REACH standards, making them suitable for regulated industries.
Professional Applications & Engineering Value
These thread forming tapping screws are engineered specifically for sheet metal applications where reliability and corrosion resistance are critical. The 18-8 stainless steel construction provides excellent durability against oxidation and chemical exposure, making them ideal for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time and costs while creating stronger thread engagement than cutting alternatives. The fully threaded design ensures consistent clamping force distribution, preventing loosening from vibration – a common challenge in automotive and industrial machinery. With their Phillips drive style and precise 11 TPI threading, these screws deliver reliable performance in high-volume production environments where speed and consistency are paramount.
Specification Summary & Compliance
This No. 12 x 2-1/2" tapping screw features a 0.216" thread diameter with 11 threads per inch precision, fully threaded design, and standard pan head profile. Manufactured from 18-8 stainless steel with Phillips No. 3 drive for secure installation. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring they meet stringent regulatory requirements for hazardous substances.
