S-90197A194 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced driving efficiency through external hex/slotted head design allowing high torque application and quick installation
• Eliminates the need for separate washers with integrated flange design that distributes clamping force and prevents pull-through
• Reduced installation effort with thread forming design that creates strong, permanent threads in sheet metal without tapping operations
• Optimal material displacement through pointed needle tip that ensures smooth penetration and secure fastening in thin materials
• Maximum thread engagement with fully threaded shank providing consistent holding power along the entire fastener length
• Precise fit and reliable performance with standardized No. 8-15 thread specification ensuring compatibility with industry-standard components

Professional Applications & Engineering Value

These zinc-plated steel flanged hex head tapping screws deliver exceptional value in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming design eliminates the need for separate nuts or tapped holes, creating strong internal threads that resist loosening under dynamic loads. The flanged hex head combines the high torque capability of external drive systems with the load distribution benefits of an integrated washer, preventing material deformation in thin-gauge metals. With a maximum drilling thickness of 0.05" and compatibility with No. 29 drill bits (0.136" diameter), these industrial fasteners provide reliable performance in HVAC systems, electronic enclosures, automotive components, and machinery assemblies where secure, permanent fastening solutions are essential for structural integrity.

Specification Summary & Compliance

This No. 8-15 x 1/2" tapping screw features precise inch system measurements with 0.164" thread diameter and 15 threads per inch. The fully threaded design with right-hand thread direction ensures consistent engagement throughout the installation depth. Manufactured to industry standards for thread forming screws, this fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components. The combination of zinc-plated steel construction and precision threading delivers reliable performance in demanding sheet metal fastening applications.
