Whether you are building some great looking 2 x 4 furniture or doing a bit of light framing, ProMax™ Optimized Thread Length™ screws will make construction easier. The extra long unthreaded shank prevents cross-threading or jacking without the need for a clearance hole, and the 1/8" length system allows use of the longest screw possible without fear of backside protrusion. These Square Drive screws have self drilling auger points, self countersinking nibs, and have a light “lube” finish suitable for interior, non-visible applications. Made in the USA/Canada/Taiwan. #2 Square Recess. Unthreaded Length 1-5/16"
ProMax™ Optimized Thread Length™: What It Means and Why You’ll Like It!Deck screws are a good example of Optimized Thread Length. The screws normally used to install 2 x 4’s or 2 x 6’s for decking are 3 inches long and have 1 inch of unthreaded shank. Since 2 x 4 and 2 x 6 deck material is 1-1/2 inches thick, the threads bridge the joint, as shown, resulting in an uneven and unsightly surface, or screws that are over-driven trying to “pull the board down.”
ProMax™ screws are different: Thread length is optimized to eliminate crossthreading, and the 1/8” length system allows use of the longest possible screw. In most cases, the smooth shank and self-drilling point allow installation without predrilling! Just select a screw that provides an unthreaded shank length equal to or slightly greater than the material thickness being fastened.

About Me Avid Do-It-Yourselfer
Really works well for keeping the boardsa pulled together. "Jacked" attachments are a thing of the past. Use not limited toi deck boards works great for anywhere you want the two pulled together tightly. Square drive best when using an impact driver. Recommend use of special undersize bits with these.
