Dependable (50-Pack) 5/16-inch x 4 1/2-inch STR Torx Star Drive Deck Framing Screws, FTC17BR516412L, 772436148167
The PWR DRIVE STR is designed to replace lag screws for framing decks or to alleviate the need for standard #10 deck screws leading to potential structural issues. The design of the STR is specific to dimensional lumber utilized in deck structures and pretty much any other framing needs for that matter, which allows maximum assembly strength. By figuring out all the possible assemblies of a structure, using a mix of 2 x 6 in (152 mm), 2 x 8 in (203 mm), 2 x 10 in (254 mm), 4 x 4 in (101.6 mm), and 6 x 6 in (152 mm), you can cover all possible combinations with only five different lengths of the STR. Fewer screws are necessary to cover anything you may encounter on the jobsite. Each pack of the STR includes a handy reference for the correct lumber combinations ideal for a specific length. Note that the required T-40 tip is included in each pack.
