The Milescraft 1.5" Pocketscrews (coarse) are self-tapping, Zinc coated T20 Star screws that are perfect for joining your work pieces together, ensuring a secure hold. The T20 Star, pan head resists cam-out better than your standard Phillips or slot head screws, allowing for a higher torque to be exerted without damaging the screw head or your tool. The coarse threads are ideal for use with softwoods or plywood. Includes 500 screws.
