Description

No predrilling! Free spiderdrive bit code compliant. Replaces 3/8 inches lag screws. 114 mm. Fastenmaster.Lok line. Meet code. Lower cost. Headlok is a heavy duty wood screw that is ideal for many wood-to-wood connections including decks, fences, headers, installing kitchen cabinets, kitchen islands and more. Guaranteed Corrosion Resistance: headlok is guaranteed not to rust or corrode for the life of the project. The coating on this fastener has been tested in wood treatment chemicals, such as ACO, and found to provide equivalent protection to code approved hot-dipped galvanized coatings. Head LOK is not recommended for use in saltwater applications (within 1,000 ft). Comparative Data: The statement Replaces 3/8 inches lags refers to the comparison of lateral (shear) design values for the Head LOK as shown in our evaluation report and lag screw values as published in the current National Design Specification for Wood Construction (NDS). See table. For critical applications, a Professional Engineer (PE) may be consulted to determine proper connection design including the number and location of fasteners to meet local code and specific load requirements.
