The Kreg 1-1/4-Inch #8 Coarse Pocket Hole Screws with Washer-Head, 100 pack, prevents overdriving in pocket bottoms, which is especially critical in composite and plywood work pieces. The self-tapping type 17 auger tip eliminates the need to predrill, and its larger diameter steel shank creates a nearly unbreakable screw. The bronze-colored finish and dry-lubricant coating improves driving torque and rust resistance.
