S-90064A584 Length 2 1/2" 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 holding power through integrated flange design that distributes clamping force over wider surface areas
• Efficient installation with external hex drive providing maximum torque transfer and secure fastening
• Self-drilling capability with No. 3 drill tip that eliminates pre-drilling requirements up to 0.187" material thickness
• Reliable thread formation through BSD thread forming design that creates strong, vibration-resistant connections in steel and sheet metal
• Full-thread engagement along the 2-1/2" length ensures maximum pull-out resistance and structural integrity
• Environmental compliance with RoHS 3 standards for safe use across regulated industries

Professional Applications & Engineering Value

These No. 12-14 thread forming tapping screws deliver exceptional engineering value in steel and sheet metal applications where vibration resistance and structural integrity are critical. The zinc-plated steel construction provides reliable corrosion protection, while the BSD thread forming technology creates permanent, high-strength threads that won't loosen under dynamic loads. The combination of external hex drive and flanged head ensures secure installation and superior clamping force distribution, making these screws ideal for HVAC systems, electrical enclosures, and metal framing applications. The integrated No. 3 drill tip eliminates secondary drilling operations, significantly reducing assembly time and labor costs in high-volume manufacturing environments.

Specification Summary & Compliance

These tapping screws feature precision No. 12-14 thread with 0.216" diameter and 14 TPI right-hand threading, manufactured to BSD standards for consistent performance. The 2-1/2" length provides full-thread engagement, while the 0.432" flange diameter ensures optimal load distribution. All components comply with RoHS 3 (2015/863/EU) environmental regulations, making them suitable for use in regulated industries and international markets requiring strict material compliance standards.
