Zinc coated Kreg screws are recommended for a wide variety of indoor projects where exposure to moisture is not a significant concern. Kreg screws are constructed of highly durable case hardened steel for the strongest possible joint. The unique design of the self-tapping tip acts as a pilot to drill its own hole in the mating workpiece to prevent your material from splitting. Coarse thread screws have larger thread diameter to provide greater holding power in softer materials such as pine, plywood and particle board. Fine thread screws are preferred choice in hardwoods as they eliminate any chance of splitting the wood. Hi-Lo thread type consists of two separate threads, one higher than the other that serves as a general purpose screw in medium hardwoods like poplar. Washer-Head (SML) with large bearing surface seats securely in bottom of pocket providing higher and more consistent clamping force on the joint line. Pan-Head (SPS) with slightly smaller head size sits below flush when joining 1/2" plywood for drawer boxes and smaller hole of Micro-Pocket joinery. Only Kreg screws are specifically designed to use with your Kreg Jig® to yield the strongest pocket hole joint possible.
