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 the risk of material pull-through in thin sheet metal.
- Efficient thread forming technology creates strong, permanent threads without chips, ideal for repeated disassembly and reassembly.
- Secure Phillips No. 2 drive provides reliable torque transmission and reduces cam-out during installation.
- Optimized for 0.025" maximum sheet thickness with precise No. 29 drill bit compatibility, ensuring accurate and fast installations.
- Full threading and pointed tip allow for quick starts and consistent engagement across the entire screw length.
- Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in global supply chains.
Professional Applications & Engineering Value
These No. 8 x 1/2" 18-8 stainless steel Phillips truss head tapping screws are engineered to address common challenges in sheet metal fabrication, such as material stripping and corrosion. The thread forming (A/AB type) design displaces material to form robust internal threads, eliminating the need for pre-tapped holes and reducing assembly time. Made from durable 18-8 stainless steel, they resist oxidation and chemical exposure, making them ideal for HVAC, electronics enclosures, and automotive panels. The wide truss head distributes clamping force over a larger area, preventing deformation in thin-gauge metals and ensuring a secure, vibration-resistant fit in demanding industrial applications.
Specification Summary & Compliance
This screw features a 0.164" thread diameter with 15 TPI in a right-hand thread direction, fully threaded for consistent holding power. Manufactured to standard thread forming (A/AB) specifications with a Class 2A inch system tolerance for reliable fit. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
