Key Features & Benefits at a Glance
- Superior torque transmission with T15 Torx drive prevents cam-out and reduces tool wear during high-torque assembly
- Enhanced corrosion resistance through zinc plating protects against rust in demanding industrial environments
- Reliable thread forming capability creates strong, permanent threads in sheet metal without chip removal
- Optimized for 0.025" maximum drilling thickness ensuring secure fastening in standard sheet metal applications
- Full 7/8" threading provides maximum grip length and uniform stress distribution
- Standard pan head design offers excellent bearing surface for consistent clamping force
- Environmental compliance meets RoHS 3 and REACH standards for safe industrial use
Professional Applications & Engineering Value
These No. 6 thread forming screws are specifically engineered for sheet metal applications where traditional cutting screws may cause material weakness. The zinc-plated steel construction provides essential corrosion protection while maintaining the high tensile strength required for industrial fastening. The T15 Torx drive system delivers exceptional torque transfer, eliminating the stripping issues common with Phillips drives in high-production environments. With their fully threaded 7/8" length and 18 TPI configuration, these thread forming screws create durable, vibration-resistant connections in metal assemblies, electrical enclosures, and HVAC systems without requiring pre-tapped holes or generating metal chips that could compromise sensitive equipment.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.138" thread diameter and Class 2A thread tolerances for consistent performance. Designed for use with No. 32 drill bit (0.116" diameter) and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand thread direction and pointed tip facilitate easy starting and proper alignment in sheet metal applications up to 0.025" thickness.
