Kreg 250-Count 1-1/4" x #7 Fine Thread Washer Head Zinc Coated Pocket-Hole Screws feature a self-tapping auger point that eliminates pre-drilling and a flat head that seats flush in the bottom of the pocket hole. The screws utilize a #2 square drive recess, and the deep recess of the square drive provides positive driver engagement to reduce cam out. 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 more protective Blue-Kote and stainless screw varieties.
