UCAN's #12-14 x 2 in. Hex-Washer-Head Tek-3 Coarse-Thread Self-Drilling Zinc-Plated Screws (3,000 Pack) provide a practical fastening option for metal-to-metal construction, fabrication, and installation work where predrilling may be unnecessary. The hex washer head allows the screw to be driven with a compatible nut driver or socket, while the self-drilling Tek-3 point is designed to penetrate metal and establish the hole during installation. Their 2 in. length provides extended reach for compatible assemblies, and the zinc-plated steel construction makes them appropriate for general indoor fastening applications where standard corrosion resistance is sufficient
