Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications
- Enhanced torque transmission through square drive pan head design, reducing cam-out and tool slippage during installation
- Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapped holes
- Full threading along 2" length provides maximum grip and uniform clamping force across entire engagement area
- Precision No. 10-12 thread configuration ensures reliable performance with standard No. 21 drill bit preparation
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and material transparency for industrial use
- Right-hand threaded pointed tip enables quick starting and smooth penetration into sheet metal up to 0.025" thickness
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 design eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The square drive pan head provides superior torque transmission compared to Phillips drives, reducing installation time and preventing fastener damage. Particularly valuable in HVAC systems, electrical enclosures, and marine equipment, these A/AB type screws maintain integrity in salt-spray environments and chemical exposures. The combination of fully threaded No. 10-12 configuration with precise 0.159" drill preparation ensures consistent performance across high-volume production runs.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread tolerances and 12 TPI thread pitch. These right-hand threaded screws feature standard pan head profile with 0.373" head diameter and square drive No. 2 compatibility. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. Designed for use with No. 21 drill bit (0.159" diameter) in sheet metal applications up to 0.025" maximum drilling thickness.
