• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 6 T15 Torx zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and holding power are critical. The thread-forming design creates permanent, strong threads in materials up to 0.025" thick, eliminating the need for separate tapping operations and reducing assembly time. The T15 Torx drive system provides superior torque transmission compared to traditional drive types, preventing tool slippage and ensuring consistent fastening pressure. The zinc-plated steel construction offers excellent corrosion resistance, making these screws ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where environmental factors may compromise fastener integrity. The combination of fully threaded design and pointed tip facilitates quick starts and smooth installation, while the pan head style distributes clamping force evenly across the material surface.

Specification Summary & Compliance

These tapping screws feature a No. 6 screw size with 0.138" thread diameter and 18 threads per inch in right-hand orientation. The fasteners are designed for use with a No. 32 drill bit (0.116" diameter) and are suitable for materials up to 0.025" maximum drilling thickness. The screws maintain standard dimensional tolerances for thread forming tapping screws and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industry standards for hazardous substance restrictions and chemical safety.
