SELF DRILL WING SCREW 12X38MM 100PER PACK

Is a premium fastening solution engineered for secure and efficient assembly of wood to metal or plywood to steel substrates. This screw features a self?drilling "TEK" point that drills, taps, and fastens in a single operation—eliminating the need for pre-drilling. Its defining innovation is the addition of small “wings” just behind the drill tip, which clear a path through soft materials like wood, before the threads engage. When the screw penetrates the harder, underlying metal, the wings break off, allowing the thread to lock in securely. This merging of drilling, tapping, and locking functions into one component significantly improves installation speed and reliability, particularly useful in flooring, roofing, and framing applications.
