S-90420A360 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with galvanic-barrier coated 18-8 stainless steel construction, ideal for harsh industrial environments
• Efficient thread forming capability creates strong, permanent threads in steel, stainless steel, and sheet metal without pre-drilling
• Integrated drilling tip penetrates up to 0.098" maximum thickness, eliminating separate drilling operations and reducing installation time
• External hex drive with flanged head provides excellent torque transmission and eliminates the need for separate washers
• Precision thread design with 18 threads per inch ensures secure fastening and vibration resistance in demanding applications
• Full threading along 1" length offers maximum grip and load distribution across the entire fastener engagement
• Environmental compliance meets RoHS 3 and REACH standards for sustainable manufacturing and safe usage

Professional Applications & Engineering Value

These No. 8-18 flanged hex head tapping screws deliver exceptional engineering value in metal fabrication and assembly operations. The galvanic-barrier coated 18-8 stainless steel construction prevents galvanic corrosion when joining dissimilar metals, while the thread forming BSD design creates stronger thread engagement than conventional cutting screws. The combination of external hex drive and integrated flange provides superior clamping force distribution, making them ideal for steel, stainless steel, and sheet metal applications where vibration resistance and structural integrity are critical. The self-drilling tip significantly reduces installation time and labor costs in high-volume production environments.

Specification Summary & Compliance

This tapping screw features precision No. 8-18 thread specifications with 0.164" thread diameter and 18 threads per inch, manufactured to industry standards for reliable performance. The BSD thread forming type ensures consistent thread engagement without material chips. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, these screws meet the highest standards for workplace safety and environmental responsibility in industrial applications.
