S-90190A204 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread-forming design creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Optimized Phillips No. 2 drive provides excellent torque transfer and reduces cam-out during installation
• Full threading with 15 TPI ensures maximum grip strength and uniform load distribution across the entire fastener length
• Precision pan head design offers low-profile installation with enhanced bearing surface for secure fastening
• Compliance with RoHS 3 and REACH standards guarantees environmental safety and regulatory acceptance for global supply chains
• Right-hand threading with pointed tip enables quick starting and smooth penetration in sheet metal applications

Professional Applications & Engineering Value

Engineered specifically for sheet metal fabrication, these thread forming tapping screws eliminate the need for pre-tapped holes, significantly reducing assembly time and labor costs. The zinc-plated steel construction provides essential corrosion protection for HVAC systems, electrical enclosures, and automotive components exposed to harsh environments. With their A/AB thread forming technology, these screws create stronger, more durable connections by displacing material rather than removing it, resulting in superior resistance to vibration loosening. The Phillips pan head design ensures flush mounting while the No. 8 diameter and 1-3/4" length provide optimal holding power for medium to heavy-gauge sheet metal applications up to 0.025" thickness.

Specification Summary & Compliance

This No. 8 x 1-3/4" tapping screw features standard inch measurements with 0.164" thread diameter and 15 threads per inch precision. Manufactured to A/AB thread forming standards with fully threaded shank and pointed tip for optimal performance in sheet metal. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. Recommended drill bit size: No. 29 (0.136" diameter) for proper thread formation.
