S-90064A741 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in demanding environments
• High-torque installation capability through external hex drive design allowing secure fastening with standard tools
• Efficient material penetration with integrated No. 3 drill tip that eliminates pre-drilling in steel and sheet metal up to 0.175" thickness
• Enhanced load distribution via integrated flange design that provides superior holding power and prevents pull-through
• Reliable thread formation through thread forming technology that creates strong, permanent threads in base materials
• Full-length fastening engagement with completely threaded shank for maximum grip along the entire 4" length
• Optimized for industrial applications with BSD tapping screw specification ensuring consistent performance in steel and sheet metal assemblies

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these No. 10-16 zinc-plated steel tapping screws deliver exceptional value in steel and sheet metal fabrication. The combination of thread forming technology and integrated drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs. The fully threaded design ensures maximum thread engagement throughout the material thickness, while the flanged hex head provides superior clamp force distribution. These BSD tapping screws are particularly valuable in construction, metal framing, and industrial equipment assembly where high-strength fastening and corrosion resistance are critical for long-term structural integrity.

Specification Summary & Compliance

This No. 10-16 x 4" tapping screw features precision right-hand threads with 0.19" thread diameter and 16 threads per inch meeting standard industrial tolerances. Manufactured as a BSD thread forming screw with external hex drive and fully threaded configuration. The zinc-plated steel construction provides corrosion protection while maintaining compliance with industry standards for tapping screws in metal applications. Designed for optimal performance in steel and sheet metal with maximum drilling capacity of 0.175" thickness using the integrated No. 3 drill tip.
