S-94425A640 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Enhanced torque transmission through T25 Torx/external hex dual-drive system preventing cam-out and tool slippage
• Self-drilling capability with No. 3 drill tip eliminates pre-drilling requirements, reducing installation time by up to 50%
• Maximum material penetration with specialized thread forming design creating permanent, vibration-resistant threads in steel and sheet metal
• Increased load distribution through 0.445" flange diameter providing superior clamping force and surface protection
• Anti-rotation security with serrated locking features maintaining fastener position under dynamic loads and vibration
• Optimized thread engagement with full-length threading ensuring consistent holding power across the entire fastener length

Professional Applications & Engineering Value

This No. 10-16 zinc-plated steel tapping screw delivers exceptional value in metal fabrication and assembly operations. The thread forming BSD design creates precise, cold-formed threads in parent material without chip removal, eliminating tapping operations and reducing labor costs. The T25 Torx drive system provides superior torque transmission compared to standard hex drives, preventing fastener damage during high-torque installation in steel and sheet metal applications. The integrated drilling tip penetrates up to 0.15" thick materials, streamlining production workflows in HVAC ductwork, electrical enclosures, and automotive assemblies. The flanged hex head with serrations distributes clamping force evenly while resisting vibration-induced loosening in demanding industrial environments.

Specification Summary & Compliance

This No. 10-16 x 3/4" tapping screw features precision right-hand threads with 16 TPI and 0.19" thread diameter meeting BSD tapping screw standards. Manufactured to Class 2A thread tolerances for consistent performance, the fastener includes a 0.313" hex head with 0.216" height and T25 Torx drive compatibility. The zinc-plated steel construction provides corrosion protection while complying with RoHS and REACH environmental standards. The thread forming design and fully threaded configuration ensure reliable performance in accordance with industrial fastening specifications for metal-to-metal applications.
