S-90064A754 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient installation with external hex drive and flanged design providing enhanced grip and preventing over-tightening
• Excellent material displacement through thread forming technology creating strong, permanent threads without chip removal
• Reduced assembly time with integrated drilling tip that eliminates pre-drilling requirements in steel and sheet metal
• Maximum holding power with fully threaded design ensuring consistent engagement along the entire 7/8" length
• Reliable performance in materials up to 0.22" thick, making them ideal for various metal fabrication applications
• Secure fastening with right-hand thread direction and BSD specification ensuring compatibility with standard industrial equipment

Professional Applications & Engineering Value

These 1/4"-14 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal applications where vibration resistance and structural integrity are critical. The thread forming design eliminates the risk of loose fasteners by creating precise, secure threads through material displacement rather than cutting. The hex head with flange provides superior torque transmission while distributing clamping force over a wider area (0.52" diameter), preventing material distortion in thin-gauge metals. The integrated No. 3 drilling tip penetrates up to 0.22" thick materials without pilot holes, significantly reducing installation time and labor costs in high-volume manufacturing environments. These BSD specification screws maintain consistent performance across repetitive assembly operations, making them ideal for automotive, HVAC, and metal enclosure applications where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to precise inch system specifications with 1/4" thread diameter and 14 threads per inch for consistent engagement. These thread forming tapping screws comply with BSD standards for reliable performance in metal fastening applications. The zinc-plated steel construction provides corrosion protection while maintaining mechanical strength. All dimensions including the 7/8" length, 3/8" head width, and 0.24" head height are manufactured to industrial tolerances ensuring compatibility with standard tools and equipment. The fully threaded design with right-hand direction follows industry-standard fastening conventions for seamless integration into existing assembly processes.
