S-93880A242 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
• Enhanced driving torque and strip-out resistance with external hex/slotted dual-drive head for reliable installation
• Excellent material retention through thread forming design that displaces rather than removes material in sheet metal
• Increased bearing surface area with 0.414" flange diameter, distributing clamp load and preventing pull-through
• Full-length thread engagement for maximum holding power across the entire 1/2" length in sheet metal applications
• Simplified installation process with blunt tip design that eliminates need for pre-tapped holes
• Environmental compliance assurance meeting RoHS 3 standards for responsible manufacturing practices

Professional Applications & Engineering Value

These No. 10-16 thread forming screws deliver exceptional performance in sheet metal fastening applications where vibration resistance and permanent assembly are critical. The zinc-plated steel construction provides reliable corrosion protection for industrial equipment, HVAC systems, and electrical enclosures. The thread forming technology creates stronger threads in ductile materials by cold-forming rather than cutting, resulting in zero chip generation and superior resistance to loosening under dynamic loads. The flanged hex head design combines the high torque capability of an external hex with the load distribution benefits of a washer, eliminating the need for separate hardware while providing secure fastening in thin-gauge materials. Engineered for use with No. 21 drill bits (0.159" diameter), these screws ensure proper hole fit for optimal thread engagement and clamping force.

Specification Summary & Compliance

This No. 10-16 x 1/2" flanged hex head tapping screw features Class 2A thread tolerances with right-hand threading and fully threaded blunt tip configuration. Manufactured to industry standards for thread forming Type B tapping screws, the fastener demonstrates compliance with RoHS 3 (2015/863/EU) environmental regulations. The combination of 0.313" head width and 0.151" head height provides optimal driver engagement, while the 0.414" flange diameter ensures sufficient load distribution for sheet metal applications up to the specified thickness.
