- Strong, reliable thread formation in sheet metal without pre-tapping, reducing assembly time and tooling requirements.
- Full-length threading and pointed tip for faster starts and consistent engagement, speeding up production line workflows.
- Precise 15 TPI thread pitch ensures tight, vibration-resistant fastening in materials up to 0.025" thickness.
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and global supply chain acceptance.
- Durable pan head design offers a low-profile, secure fit with improved load distribution.
Professional Applications & Engineering Value
These No. 8 x 3/4" Tri-Wing® tapping screws are engineered to address common challenges in sheet metal assembly, such as material splitting and loose fasteners under stress. The 18-8 stainless steel provides excellent resistance to oxidation and chemicals, extending service life in HVAC, electronics enclosures, and automotive panels. The thread forming design displaces material to create strong, permanent threads without chips, eliminating the need for threaded inserts and reducing installation steps. With a right-hand thread direction and fully threaded shank, these screws ensure uniform clamping force and rapid driving, making them a reliable choice for high-volume manufacturing and maintenance operations requiring corrosion-resistant fasteners.
Specification Summary & Compliance
This screw features a No. 8 size with a 0.164" thread diameter and 15 TPI precision, adhering to standard thread forming (Type A/AB) specifications for consistent performance. The Tri-Wing® drive (Size No. 4) and pan head profile ensure secure torque application. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting sustainable procurement practices in industrial applications.
