Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide steel coating for extended service life in demanding industrial environments
- Efficient thread forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
- Optimized Phillips No. 2 drive ensures secure tool engagement and reduces cam-out during installation
- Full threading and pointed tip enable faster starts and smoother driving through sheet metal substrates
- Precision-matched drill bit compatibility (No. 32/0.116") simplifies installation planning and reduces assembly time
- Pan head design provides excellent bearing surface for secure fastening without sinking into materials
- Regulatory compliance assurance with RoHS 3 and REACH standards for global manufacturing applications
Professional Applications & Engineering Value
These No. 6 x 3/8" Phillips Pan Head tapping screws are specifically engineered for sheet metal applications where reliability and installation efficiency are critical. The black-oxide steel construction provides enhanced corrosion protection, making these thread forming screws ideal for HVAC systems, electrical enclosures, and automotive assemblies. The A/AB tapping screw type with 18 TPI thread form creates durable, vibration-resistant connections by displacing material rather than removing it, resulting in stronger thread engagement. The combination of fully threaded design and pointed tip ensures quick starts and consistent performance across various sheet metal thicknesses, reducing installation time and improving production throughput in industrial manufacturing environments.
Specification Summary & Compliance
These precision-engineered tapping screws feature a 0.138" thread diameter with 18 TPI right-hand threading and Class 2A thread tolerances for consistent performance. The fasteners are designed for use with No. 32 drill bits (0.116" diameter) and accommodate maximum drilling thickness of 0.025". Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met for global industrial applications.
