Sheet Metal Screws

Our Pull-Tight sheet metal screws are the best product on the market. The serrated hex washer head self-piercing and self-drilling screws provide superior starting and holding power compared to standard sheet metal screws. Pull-Tight screws have a special serrated washer design that pulls in material for full engagement and have flanged teeth under the head that virtually eliminates stripping. The self-piercing screws penetrate best in material up to 16 gauge and the self-drilling screws are best for heavier gauge materials. Both products are designed to be installed with power tools for quick installation. They are made of heat-treated steel and have an improved corrosion resistant zinc finish. Sizes in stock range from #6 x 1/2" to #14 x 1-1/2".

Let us show you the difference that superior customer service can make for your business.
