- Flanged truss head design offers superior load distribution and prevents pull-through in thin materials
- Fully threaded length ensures maximum grip and holding power across the entire fastener engagement
- Thread forming BSD type creates strong, secure threads in parent material without chip formation
- No. 3 drill tip efficiently penetrates materials up to 0.175" thick for versatile application range
- Phillips No. 2 drive enables efficient installation with common industrial tools
Professional Applications & Engineering Value
This heavy-duty tapping screw delivers exceptional value in steel and sheet metal fabrication where speed and reliability are critical. The zinc-plated steel construction withstands harsh industrial conditions while the self-drilling No. 3 tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs. The flanged truss head provides a wide bearing surface that distributes clamping force effectively, preventing material distortion in thin-gauge applications. As a thread forming BSD type screw, it creates precise, strong threads without generating chips, ensuring clean, secure fastening in structural assemblies, HVAC systems, and metal framing projects where vibration resistance and long-term performance are essential.
Specification Summary & Compliance
This No. 10-16 x 4-1/2" tapping screw features a 0.19" thread diameter with 16 threads per inch in right-hand orientation. Manufactured to BSD tapping screw standards with Class 2A thread tolerances, the fastener includes a fully threaded round shank and wide truss head profile. The product is fully RoHS 3 (2015/863/EU) compliant for use in regulated industrial applications, meeting environmental and safety requirements for professional use.
