The Grabber 508XX drywall screws are used to attach drywall, sheetrock, or gypsum board to wood and come in a 20 pound box (approx. 3,500 screws). Grabber's Pro-Fit recess is designed for better bit engagement resulting in less wobble, strip-out, or cam-out. Signature Scavenger head is a double Bugle head design that seats cleanly into drywall eliminating the potential for paper burrs. For gypsum board, the Scavenger head is fully seated when the screw is below the surface of the wallboard in accordance with Section 7.2.2 of ASTM C1002.The extra sharp 23° Grabber point design starts immediately and is much less likely to flop over. Grabber screws begin with the best available materials and conform to strict manufacturing requirements with less stress during the milling process, resulting in a stronger screw. Grabber screws use the highest quality cold heading SAE 1022 steel wire, which forms stronger, superior heads and threads for consistent screws that are less likely to break or bend. This means fewer wasted screws. Drive more screws in less time with a cleaner, smoother finish and less waste. That's the Grabber value. Available in various lengths and finishes, including superior corrosion protection.
