- Wide truss head profile provides a larger bearing surface for improved load distribution and reduced risk of pull-through
- Reliable Phillips No. 2 drive ensures common tool compatibility and consistent torque application during installation
- Precision thread engagement with No. 6-18 right-hand threads (0.138" diameter) for strong, vibration-resistant connections
- Compliance with global standards including RoHS 3 and REACH, ensuring safety and environmental responsibility for industrial use
Professional Applications & Engineering Value
These 316 stainless steel Phillips truss head tapping screws are engineered to address common challenges in sheet metal fabrication and assembly. The thread forming (Type A/AB) technology creates strong, clean threads in ductile materials without generating chips, preventing contamination in sensitive equipment. The wide truss head design distributes clamping force effectively, minimizing sheet distortion and improving joint integrity. With full threading and a pointed tip, they ensure rapid startup and deep penetration, making them ideal for high-volume production lines in HVAC, electronics enclosures, and automotive components where corrosion resistance and reliability are critical.
Specification Summary & Compliance
This screw meets standard inch dimensions: No. 6-18 thread (0.138" diameter, 18 TPI), 1/2" length, Class 2A fit. It features a rounded truss head (0.321" diameter, 0.086" height) with Phillips No. 2 drive and is fully threaded. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to industrial safety and environmental standards for hazardous substance restrictions.
