Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
- Enhanced load distribution from the wide truss head design, reducing surface pressure and preventing material damage in sheet metal applications.
- Efficient thread forming technology that creates strong, permanent threads without chips, ideal for repeated assembly and disassembly.
- Secure Phillips No. 3 drive provides reliable torque transmission and reduces the risk of cam-out during installation.
- Full threading and pointed tip for quick, self-tapping starts and consistent holding power across the entire 1/2" length.
- Compliance with RoHS 3 and REACH standards guarantees safety and environmental responsibility for industrial use.
- Optimized for 5.5 mm drill bits, ensuring precise fit and maximum drilling thickness up to 0.025" in sheet metal.
Professional Applications & Engineering Value
These No. 14 Phillips truss head tapping screws are engineered to address common challenges in sheet metal fabrication, such as material stripping and corrosion. The 18-8 stainless steel offers excellent resistance to rust and oxidation, while the thread forming (Type A/AB) design creates durable, high-strength threads that withstand vibration and load stresses. The wide truss head distributes clamping force evenly, preventing deformation in thin-gauge metals. Ideal for HVAC systems, electronic enclosures, and automotive panels, these screws ensure reliable fastening without pre-tapped holes, streamlining production and reducing assembly time.
Specification Summary & Compliance
This screw features a 0.242" thread diameter with 10 threads per inch and a 1/2" fully threaded length, adhering to standard inch measurements for precision. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances are used. The thread forming tapping method and right-hand threading provide consistent performance in industrial settings, meeting common engineering requirements for sheet metal fasteners.
