S-90420A460 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.15" thick steel, stainless steel, and sheet metal
• Superior corrosion resistance through galvanic-barrier coated 18-8 stainless steel construction for extended service life in harsh environments
• Maximum torque transmission with external hex drive design that prevents cam-out and ensures secure installation
• Enhanced load distribution from the integrated flange that eliminates the need for separate washers and provides superior clamping force
• Reliable thread formation through BSD thread forming design that creates strong, permanent threads in base materials
• Full-length engagement capability with completely threaded shank for maximum holding power across the entire fastener length
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industrial applications

Professional Applications & Engineering Value

These flanged hex head tapping screws deliver exceptional value in metal fabrication and assembly operations where time efficiency and joint integrity are critical. The galvanic-barrier coated 18-8 stainless steel construction prevents galvanic corrosion when joining dissimilar metals, while the thread forming BSD design creates precisely formed threads that resist vibration-induced loosening. The combination of external hex drive and integrated drilling tip eliminates multiple processing steps in steel, stainless steel, and sheet metal applications, significantly reducing installation time and labor costs. The fully threaded configuration ensures uniform stress distribution, making these industrial fasteners ideal for high-vibration environments where joint reliability is paramount.

Specification Summary & Compliance

This No. 10-16 x 1" tapping screw features precision right-hand threads with 16 threads per inch and Class 2A thread tolerances for consistent performance. Manufactured to BSD tapping screw standards with a No. 3 drill tip type capable of penetrating 0.15" maximum thickness. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
