Whether you are building some great looking 2 x 4 furniture or doing a bit of light framing, ProMax™ Optimized Thread Length™ wood 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 flat head wood 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 13/16"
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.

I've used these screws before
from Stone Mountain, GA
I use these screws to secure sub-floors to joists prior to laying hardwood floors. They are easy to use, fast starting, drive straight, drive home securely and countersink themselves well due to the nibs on the underside of the screw head. I also use these screws for many woodworking applications.
