S-90106A108 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 410 Stainless Steel construction for long-lasting performance in demanding industrial environments
• Superior installation efficiency through combined drilling tip and thread-forming design that eliminates pre-drilling requirements
• Secure flange retention with 0.348" diameter providing reliable bearing surface and eliminating the need for separate washers
• High-torque capability with external hex drive design ensuring secure fastening in steel and sheet metal applications
• Maximum material penetration featuring 0.098" maximum drilling thickness capability for robust connections in metal substrates
• Full-length threading delivering consistent holding power along the entire 1" screw length for superior fastening integrity
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 8-18 TPI flanged tapping screws deliver exceptional engineering value in steel, stainless steel, and sheet metal applications where traditional fastening methods fall short. The 410 Stainless Steel composition provides excellent corrosion resistance, while the thread-forming BSD design creates stronger, more reliable threads in parent material without chip formation. The integrated drilling tip penetrates up to 0.098" thickness, eliminating secondary drilling operations and reducing assembly time. The external hex drive ensures high torque transmission during installation, and the built-in flange distributes clamping force evenly, preventing material distortion in thin-gauge applications. This comprehensive solution addresses common industrial challenges including vibration resistance, corrosion protection, and installation efficiency.

Specification Summary & Compliance

This No. 8-18 x 1" flanged tapping screw features precise 0.164" thread diameter with 18 TPI right-hand threads in a fully threaded configuration. Manufactured to BSD screw type standards for thread-forming applications, it includes a No. 2 drilling tip with 3/16" tip length. The fastener maintains dimensional accuracy with 1/4" hex head width and 0.141" head height. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and industrial safety standards.
