S-93880A194 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 holding power through thread forming technology that creates stronger, more permanent threads in sheet metal
• Efficient installation with dual external hex/slotted drive options providing flexibility for various tool applications
• Eliminates need for separate washers with integrated flange design that distributes load evenly and prevents pull-through
• Maximum thread engagement with fully threaded design ensuring consistent holding strength along the entire fastener length
• Simplified assembly process with blunt tip design that aligns easily with pre-drilled holes for faster installation
• Regulatory compliance assurance with RoHS 3 certification for environmentally responsible manufacturing standards

Professional Applications & Engineering Value

These thread forming tapping screws deliver exceptional performance in sheet metal assembly applications where vibration resistance and permanent fastening are critical. The Type B thread forming design displaces material rather than removing it, creating zero-clearance threads that significantly improve holding power and resistance to loosening under stress. The zinc-plated steel construction provides reliable corrosion protection for industrial environments, while the flanged hex head combines the installation torque capability of an external hex with the load distribution benefits of an integrated washer. Engineered for use with No. 29 drill bits (0.136" diameter), these screws ensure precise fitment in pre-drilled holes, making them ideal for HVAC systems, electrical enclosures, automotive components, and machinery assemblies where durable metal-to-metal fastening is essential.

Specification Summary & Compliance

This No. 8-18 x 1/2" flanged hex tapping screw features a 0.164" thread diameter with 18 threads per inch in right-hand orientation and Class 2A thread tolerances for consistent performance. The thread forming Type B design complies with industry standards for self-tapping fasteners in sheet metal applications. Manufactured from zinc-plated steel with a 1/4" hex head width and 0.348" flange diameter, this fastener is RoHS 3 (2015/863/EU) Compliant, ensuring adherence to environmental regulations for industrial components.
