Download or read book Screw withdrawal resistance of types A and AB sheet metal screws in particleboard and medium density hardboard written by Michael J. Superfesky and published by . This book was released on 1974 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common type A sheet metal screw has been replaced by type AB. To compare the face and edge withdrawal resistance of types A and AB screws, the Forest Products Laboratory evaluated their performance in eight particleboards and three medium-density hardboards. All testing was conducted in accordance with ASTM D 1037-72 except a 0.136-inch-diameter pilot hole was used to facilitate insertion of the screws. In the particleboards, face withdrawal resistance of type AB screws averaged approximately 5 percent less than for type A screws. Results for edge withdrawal in particleboard were erratic because of the differences in makeup of the center portion of each board. In the hardboards, average face and edge withdrawal resistance of type AB screws was approximately 10% less than of type A screws.
