Abstract

598,834. Wood-screws. THOMPSON, E. C. Sept. 20, 1945, No. 24332. [Class 89 (ii)] The shank of a wood-screw has a number of grooves b so arranged, with regard to the axis of the screw, that unscrewing is resisted. The angle between the sides c, d may be less than a right angle and the corner e is preferably radiused.
