Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments.
- Efficient thread forming design creates strong, reliable threads in sheet metal without pre-tapping, reducing installation time.
- Secure Phillips No. 2 drive provides excellent torque transfer and reduces cam-out during installation.
- Decorative and functional oval head offers a smooth, finished appearance while sitting flush with the material surface.
- Optimized for 0.025" maximum sheet metal thickness ensuring reliable fastening in standard industrial applications.
- Full threading along the 1/2" length delivers maximum grip and holding power in thin materials.
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and global market acceptance.
Professional Applications & Engineering Value
These 18-8 stainless steel oval head Phillips tapping screws are specifically engineered for sheet metal applications where corrosion resistance and installation efficiency are critical. The thread forming Type A/AB design displaces material to create permanent, high-strength threads without chips, eliminating the need for separate tapping operations. This makes them ideal for assembly lines in HVAC, electronics enclosures, and automotive panels where vibration resistance and durability are paramount. The combination of fully threaded shanks and precise 82° countersink angle ensures flush mounting and uniform stress distribution, preventing material deformation while maintaining structural integrity in thin-gauge metals.
Specification Summary & Compliance
This No. 6 x 1/2" tapping screw features a 0.138" thread diameter with 18 TPI fully threaded shank, manufactured to standard thread forming Type A/AB specifications. Precision-engineered with Class 2A thread tolerances for consistent performance, it requires a No. 32 drill bit (0.116" diameter) for proper hole preparation. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and consumer applications worldwide.
