Professional Applications & Engineering Value

This No. 8-18 TPI hex flange tapping screw delivers exceptional performance in sheet metal assembly applications where reliability is critical. The thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement through material displacement rather than cutting. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the integrated flange design distributes clamping force over a wider area, reducing the risk of material deformation. The combination of external hex and slotted drive options offers installation flexibility for both power and manual tools, making these Type B tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and machinery assembly where vibration resistance and long-term fastener integrity are paramount.

Specification Summary & Compliance

This precision-engineered tapping screw features a No. 8 size with 18 threads per inch and 3/8" length, manufactured to exacting dimensional standards with 0.164" thread diameter and 1/4" hex head width for consistent performance. The thread forming (Type B) design creates secure fastening in sheet metal applications when used with the recommended No. 29 drill bit (0.136" diameter). All components are RoHS 3 (2015/863/EU) compliant, ensuring environmental responsibility while meeting industrial durability requirements for right-hand threaded, fully threaded fasteners with blunt tip configuration.
