S-90190A291 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Excellent driving control with Phillips No. 3 drive and pan head design, preventing cam-out during high-torque applications
• Maximum material engagement through fully threaded design and pointed tip, ensuring secure fastening in sheet metal up to 0.025" thickness
• Reliable performance with A/AB tapping screw specification, providing consistent thread engagement and holding power
• Precision dimensional accuracy with 0.216" thread diameter and 11 threads per inch, ensuring proper fit and reduced stripping risk
• Environmental compliance meeting RoHS 3 and REACH standards for safe use across regulated industries

Professional Applications & Engineering Value

These No. 12 x 1/2" zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for separate tapping operations, creating strong, clean threads that won't loosen under stress. The Phillips pan head design provides reliable drive engagement while the fully threaded configuration ensures maximum holding power throughout the entire fastener length. These industrial screws are particularly valuable in metalworking, HVAC systems, and electrical enclosures where sheet metal fasteners must maintain integrity despite thermal cycling and mechanical loads. The combination of zinc-plated steel material and precision thread forming screws addresses common failure points in metal assembly applications.
