S-90420A470 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with galvanic-barrier coated 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Enhanced installation efficiency through the integrated drilling tip that eliminates pre-drilling, saving labor time and costs
• Maximum material penetration with 0.15" maximum drilling thickness capability for secure fastening in steel and sheet metal applications
• Secure anti-loosening performance thanks to the flanged hex head design that provides superior clamp load and vibration resistance
• Optimized thread engagement with fully threaded design and thread forming tapping method for strong, permanent connections
• Easy installation and removal with external hex drive that accommodates standard tools while preventing cam-out
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 10-16 flanged hex head tapping screws deliver exceptional engineering value in demanding metal fabrication applications. The galvanic-barrier coated 18-8 stainless steel construction prevents galvanic corrosion when joining dissimilar metals, while the precision thread forming design creates stronger threads in parent materials without chip formation. The integrated drilling tip eliminates secondary operations in steel, stainless steel, and sheet metal assemblies, significantly reducing installation time and labor costs. The flanged hex head provides wider bearing surface distribution, preventing pull-through in thin materials and maintaining clamp force under vibration. These BSD tapping screws are engineered to solve common industrial challenges including corrosion protection, installation efficiency, and long-term joint integrity in structural applications.

Specification Summary & Compliance

This No. 10-16 x 1-1/4" flanged hex head tapping screw features a 0.19" thread diameter with 16 threads per inch and Class 2A thread tolerances. Manufactured as BSD type thread forming screws with fully threaded design and 7/32" No. 3 drill tip. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial compliance standards for hazardous substance restrictions.
