S-93406A252 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Enhanced holding power provided by the wide rounded truss head design that distributes load over a larger surface area
• Efficient thread forming capability creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Maximum material penetration with fully threaded design and pointed tip for quick, secure installation in sheet metal applications
• Optimized drilling compatibility with No. 21 drill bit (0.159") for precise hole preparation up to 0.025" thickness
• Reliable drive engagement through Phillips No. 2 drive system that minimizes cam-out during installation
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe industrial use

Professional Applications & Engineering Value

This No. 10 x 1-3/4" tapping screw delivers exceptional engineering value for sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides outstanding corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor elements. The thread forming technology (A/AB type) eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, vibration-resistant connections. The Phillips truss head design offers superior clamping force distribution, preventing material distortion in thin-gauge metals. With fully threaded construction and right-hand threading at 12 threads per inch, this fastener ensures maximum thread engagement and pull-out resistance in various sheet metal thicknesses.

Specification Summary & Compliance

This thread forming sheet metal screw features precise dimensional specifications including No. 10 screw size, 1-3/4" length, 0.19" thread diameter, and 12 threads per inch. The fastener is manufactured to industry standards for A/AB tapping screw types with proper thread form and geometry. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance management. The screw is optimized for use with No. 21 drill bit (0.159" diameter) and maximum drilling thickness of 0.025" in sheet metal applications.
