Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life
- Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
- No. 3 Phillips drive provides secure tool engagement and prevents cam-out during high-torque applications
- Fully threaded shank ensures maximum grip length and uniform stress distribution across the entire fastener
- Pan head profile offers low-profile installation with excellent bearing surface for secure fastening
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets industrial standards
- Precision-engineered dimensions (0.216" thread diameter, 11 TPI) ensure consistent performance in sheet metal applications
Professional Applications & Engineering Value
These 316 Stainless Steel tapping screws are specifically engineered for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design (Type A/AB) displaces material rather than removing it, creating stronger threads that resist vibration loosening and provide superior pull-out strength. The fully threaded configuration ensures maximum engagement in thin materials up to 0.025" thickness, while the Phillips pan head delivers reliable clamping force without protruding excessively. Ideal for HVAC systems, electronic enclosures, and industrial equipment, these screws solve common challenges like galvanic corrosion, thread stripping, and installation efficiency in metal working environments.
Specification Summary & Compliance
This No. 12 x 1/2" tapping screw features right-hand threads with approximately 11 threads per inch and a 0.216" thread diameter. Manufactured to standard thread forming specifications (Type A/AB) with Class 2A thread tolerances for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial applications.
