10 x 3 Simpson Bugle-Head Wood Decking Screws - 6-Lobe Drive 316 SS - 1 lbs Pack (68) . 6-lobe drive prevents driver bit cam-out and stripping in recess. Type 17 tip provides fast starts and prevents splitting in hardwoods. Coarse threads run approximately 2/3 up the shank to help draw the decking tightly to the substrate. Pre-drilling is recommended near board-ends to prevent splitting. 316 stainless steel is ideal where superior corrosion resistance is required.
