- Pan head design offers a low-profile finish with good bearing surface for secure fastening
- Regulatory compliance meets RoHS 3 and REACH standards for environmentally responsible manufacturing
Professional Applications & Engineering Value
These 316 stainless steel tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance is critical. The thread forming Type A/AB design creates strong, permanent threads in ductile materials without generating chips that could contaminate sensitive equipment. The combination of 18 TPI thread pitch and 0.138" thread diameter provides optimal thread engagement in thin materials up to 0.025" thickness. The pan head with square drive ensures reliable installation in high-volume production environments, while the fully threaded configuration maximizes pull-out strength. These features make these fasteners ideal for HVAC systems, electronic enclosures, automotive components, and marine applications where vibration resistance and long-term durability are essential.
Specification Summary & Compliance
These inch-system fasteners feature a No. 6 diameter with 18 TPI right-hand threads and Class 2A thread tolerances. The thread forming Type A/AB design follows industry standards for sheet metal applications with recommended No. 32 drill bit (0.116" diameter) for optimal performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met.
