Use these on your next project and you’ll wonder why screws haven’t been designed like this all along. McFeely’s ProMax® screws are designed with a thread length for the common usage of the screw. For example: A 2-3/8” screw used to install 5/4” decking needs slightly more than 1” of smooth shank, while a 2-7/8” screw used to install 1-1/2” thick 2x stock needs more. These ProMax® screws have self-drilling auger points, self -countersinking nibs, and our special NoCoRode “Plus”corrosion-resistant finish. Use NoCoRode Undersized driver bits for best results. They are specially designed with undersized tips that fit the recess of NoCoRode PLUS plated screws perfectly. Made in Taiwan or China. Unthreaded Length 1-9/16"
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 have been using these for years and have never seen any rust. I just finished a large deck using an autofeed screw gun with screws that had a traditional thread design. I had a constant problem getting the deck boards tight to the joists. So I used these screws with their ProMax thread design on all the board ends and other places where the deck boards where not tight to the joists and they worked great!
