About This Product
FastenMaster HeadLOK is a heavy-duty wood screw designed for quick, efficient fastening with an internal drive and flat head. Offering higher shear strength than 3/8" lag screws, HeadLOK eliminates the need for predrilling and installs easily for a clean, finished look. Perfect for wood-to-wood applications such as decks, fences, and kitchen cabinets. The patented SpiderDrive 8-point star bit prevents cam-out and enhances installation speed. The black-coated, flat-head design is ideal for those seeking superior craftsmanship. HeadLOK is built to last for the lifetime of the project. This set includes 50 screws (4-1/2 inches) and one SpiderDrive bit. First introduced in 2007, HeadLOK was the industry's first flat-headed structural fastener to meet code requirements, trusted by both pros and DIYers for various applications.
