S-93880A148 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 installation efficiency through external hex/slotted drive compatibility with both manual and power tools
• Exceptional holding power achieved through thread forming technology that creates stronger, more permanent threads in sheet metal
• Increased stability and load distribution thanks to the integrated flange design that eliminates the need for separate washers
• Full-length threading provides maximum engagement and pull-out resistance throughout the entire fastener length
• Precision compatibility with No. 32 drill bits (0.116" diameter) ensures proper fit and optimal performance in pre-drilled holes
• Environmental compliance assurance with RoHS 3 certification for safe use in regulated applications

Professional Applications & Engineering Value

These No. 6-20 thread forming tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The zinc-plated steel construction provides reliable corrosion protection while maintaining the strength required for industrial use. The thread forming design eliminates the need for tapping operations by displacing material to create stronger, zero-clearance threads that won't loosen under vibration. The combination of external hex/slotted drive offers versatility for both high-torque installation and quick adjustments. The integrated flange feature distributes clamping force evenly, preventing material distortion in thin-gauge sheet metal while the fully threaded blunt tip ensures smooth engagement without damaging adjacent components.

Specification Summary & Compliance

This No. 6-20 x 1/2" tapping screw features precision inch system measurements with a thread diameter of 0.138" and 20 threads per inch. Manufactured to industry standards for thread forming Type B screws with right-hand threading and fully threaded shank. The fastener is designed for use with No. 32 drill bits (0.116" diameter) in sheet metal applications. Compliant with RoHS 3 (2015/863/EU) regulations for environmental safety and restricted substance control, ensuring suitability for various industrial and commercial applications requiring certified components.
