S-90628A305 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with specialized coating extends service life in harsh industrial environments
• Integrated steel/rubber sealing washer creates reliable moisture and dust barriers in outdoor applications
• Self-drilling tip design eliminates pre-drilling requirements, reducing installation time by up to 50%
• Thread forming BSD technology creates stronger, more vibration-resistant threads in steel and sheet metal
• External hex drive system provides maximum torque transmission and prevents tool slippage
• Full threading along 2-1/2" length ensures uniform load distribution and superior holding power
• Heavy-duty construction withstands extreme mechanical stress in structural steel applications

Professional Applications & Engineering Value

These No. 12 x 2-1/2" tapping screws deliver exceptional engineering value for steel and sheet metal fabrication where corrosion protection and sealing integrity are critical. The corrosion-resistant coated steel construction prevents rust formation in humid or chemical environments, while the thread forming BSD design creates permanent, high-strength threads without material removal. The integrated steel/rubber sealing washer solves common leakage issues in outdoor enclosures and HVAC systems, and the self-drilling tip penetrates up to 0.187" thickness, eliminating secondary drilling operations. These fully threaded screws with external hex drive provide reliable fastening in structural frameworks, industrial machinery, and metal building components where vibration resistance and long-term durability are essential.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.216" thread diameter and 14 TPI right-hand threads, these BSD tapping screws meet industry threading specifications for reliable performance. The Class 2A thread tolerance ensures consistent fit and function across production runs. Compliant with RoHS and REACH environmental standards, these industrial fasteners are manufactured using quality-controlled processes suitable for demanding steel and sheet metal applications requiring corrosion resistance and mechanical reliability.
