About This Product

FastenMaster HeadLOK is a heavy-duty wood screw featuring an internal drive and flat head. It provides greater shear strength than 3/8 in. lag screws without the need for predrilling. HeadLOK installs quickly and delivers a clean, professional finish. It’s perfect for a variety of wood-to-wood projects such as decks, fences, and kitchen cabinets. The patented SpiderDrive 8-point star bit prevents cam-out and speeds up installation. Its sleek black coating and flat head design offer an attractive, polished look. Includes 12, 4-1/2 in. flat head wood screws and 1 SpiderDrive bit. Since its introduction in 2007, HeadLOK has been a trusted flat-headed structural fastener for both professionals and DIYers.
