Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments
- Enhanced load distribution from the wide truss head design, reducing material stress and preventing pull-through
- Efficient thread forming eliminates the need for pre-tapped holes, saving installation time and labor costs
- Full threading provides maximum grip along the entire 2" length for secure sheet metal fastening
- Optimized compatibility with No. 21 drill bits (0.159" diameter) for precise hole preparation
- Reliable Phillips drive (No. 2 size) ensures common tool compatibility and controlled torque application
- Environmental compliance with RoHS 3 and REACH standards for global industrial applications
Professional Applications & Engineering Value
These No. 10-12 thread tapping screws are specifically engineered for sheet metal applications where vibration resistance and material integrity are critical. The 18-8 stainless steel composition provides exceptional corrosion resistance, making these thread forming screws ideal for outdoor equipment, HVAC systems, and electrical enclosures exposed to moisture. The wide truss head design distributes clamping force over a larger surface area, preventing deformation of thin gauge materials while the fully threaded configuration ensures maximum engagement in assemblies up to 0.025" thickness. This combination of corrosion resistant material and optimized geometry delivers reliable performance in demanding industrial environments.
Specification Summary & Compliance
This No. 10 tapping screw features a 0.19" thread diameter with 12 threads per inch in right-hand orientation, manufactured to standard thread forming (Type A/AB) specifications. The Phillips truss head screw maintains precise dimensional tolerances with 0.448" head diameter and 0.118" head height. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. Designed for use with No. 21 drill bits (0.159" diameter) in sheet metal applications requiring maximum drilling thickness of 0.025".
