S-90197A199 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Enhanced holding power through thread-forming needle design that creates strong, permanent threads in sheet metal
• Efficient installation with external hex/slotted drive that accommodates multiple tool types for versatile application
• Maximum material engagement with fully threaded shank design that distributes load evenly across the entire fastener length
• Eliminates need for separate washers with integrated flange that provides wider bearing surface and prevents pull-through
• Optimized for thin materials with 0.05" maximum drilling thickness capability and No. 29 drill bit compatibility
• Reliable thread engagement with 15 threads per inch providing secure fastening in sheet metal applications

Professional Applications & Engineering Value

This zinc-plated steel flanged hex tapping screw delivers exceptional performance in sheet metal fastening applications where vibration resistance and permanent installation are critical. The thread-forming needle point eliminates the need for pre-tapped holes, creating precise mating threads that significantly reduce installation time while providing superior pull-out resistance compared to conventional screws. The external hex/slotted drive system offers dual-tool compatibility, allowing technicians to use either hex drivers or flathead screwdrivers based on accessibility constraints. The integrated flange design distributes clamping force over a wider area, preventing material deformation in thin-gauge sheet metal while eliminating the cost and inventory of separate washers. These fully threaded screws maintain consistent holding power throughout their entire length, making them ideal for applications where maximum thread engagement is essential for structural integrity.

Specification Summary & Compliance

This No. 8-15 x 1" tapping screw features a 0.164" thread diameter with 15 threads per inch right-hand threading and fully threaded configuration. The fastener is manufactured to precise dimensional standards with a 1/4" hex head width and 0.141" head height for consistent tool engagement. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures these screws meet the latest international standards for hazardous substance restrictions, making them suitable for global supply chains and environmentally conscious manufacturing operations.
