Have the best screws on hand for soft wood outdoor projects using Kreg's 1-1/2" #8 Blue-Kote WR Pocket Screws, 100 Pack (SML-C150B-100). Made of case-hardened steel, the screws won't bend or break, making them nearly unbreakable. The washer head prevents overdriving in pocket bottoms, which is critical in composite and plywood work pieces. Ideal for projects involving 7/8"- and 1-1/8"-thick softwood, the Blue-kote finish features 3 corrosion-resistent layers for heavy-duty corrosion resistance in the outdoors.  The large maxi-loc head provides incredible hold strength while the deep square drive gives you optimum driver engagement. Plus, the self-tapping auger tip drills its own hole while being driven, conveniently eliminating the need to pre-drill.
