FastenMaster HeadLok Screw 6 in. (50-Pack)

Elevate your wood-to-wood construction with the FastenMaster HeadLok 6 in. structural wood screw. Featuring an aggressive gimlet point and patented Spider Drive, these screws zip into pressure-treated lumber and engineered wood without predrilling—saving you time and labor on deck framing, stair stringers, fencing, cabinets and more. With design shear values that outperform 3/8″ lag screws and ACQ-approved corrosion resistance, HeadLok delivers professional-grade performance every time.

Designed for durability and ease of use, each package includes a free Spider Driver bit so you’re ready to go straight out of the box. The flat-wafer head sits flush for a clean finish, while the double-square drive virtually eliminates cam-out even under heavy loads. Whether you’re a contractor or a weekend warrior, HeadLok screws make fast work of your toughest projects.
