• Enhanced material engagement through thread forming technology that creates stronger, vibration-resistant connections
• Optimized for steel and sheet metal applications with capability to drill through up to 0.098" thickness
• Secure flange design provides wider bearing surface for improved load distribution and stability
• Easy installation and removal with standard 1/4" external hex head compatible with common tools
• Full threading ensures maximum grip length and consistent holding power throughout the fastener

Professional Applications & Engineering Value

This No. 8 zinc-plated steel flanged tapping screw delivers exceptional performance in steel and sheet metal fabrication where speed and reliability are critical. The integrated drilling tip eliminates secondary drilling operations, significantly reducing installation time and labor costs in high-volume production environments. The thread forming design creates precise mating threads without generating chips, preventing contamination in sensitive electrical enclosures and HVAC systems. With its flanged hex head configuration, this fastener provides superior clamping force distribution while resisting pull-through in thin-gauge materials. The zinc-plated finish offers essential corrosion protection for both indoor industrial equipment and outdoor applications exposed to moderate environmental conditions.

Specification Summary & Compliance

This BSD tapping screw features a No. 8 size with 0.164" thread diameter and 18 TPI right-hand threading, fully compliant with industry standards for thread forming fasteners. The 9/16" length and fully threaded design ensure consistent performance across various material thicknesses. Manufactured to precise dimensional tolerances with a 1/4" hex head and integrated flange, this screw meets quality specifications for industrial fastening applications. The construction complies with relevant industry standards for heavy-duty fasteners used in steel and sheet metal assemblies.
