S-90190A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum holding power through thread forming technology that creates strong, permanent threads in sheet metal without chip removal
• Reliable installation with Phillips No. 2 drive design that prevents cam-out and ensures consistent torque application
• Optimized for thin materials with capability to fasten sheet metal up to 0.025" thickness without pre-tapped holes
• Enhanced grip and alignment from the pan head design that provides a larger bearing surface for secure fastening
• Quick penetration with pointed tip and fully threaded shank that enables fast installation and strong thread engagement
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal applications where traditional fastening methods fall short. The thread forming technology eliminates the need for pre-tapped holes, creating strong, vibration-resistant connections that won't loosen under stress. The Phillips drive system ensures consistent installation torque while the A/AB thread type provides optimal performance in various metal thicknesses. Ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment, these screws solve common challenges of strip-out, cross-threading, and material deformation. The fully threaded design with 15 threads per inch offers maximum thread engagement, while the zinc plating provides essential corrosion protection for long-term reliability in harsh environments.
