Kreg Zinc Screws are a good choice for a wide variety of indoor projects with limited exposure to the elements. Zinc screws provide adequate rust protection, and serve as an affordable alternative to our more protective Blue-Kote and stainless screw varieties. Available in a variety of sizes, thread options, head styles, and quantities. The Kreg 1-1/4-Inch #7 Fine Pocket Hole Screws with Pan-Head is ideal for 3/4-inch thick hardwood work pieces. The washer head 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 zinc-colored finish and dry-lubricant coating improves driving torque and rust resistance. This pack includes 500 hole screws.
