A method for the production of a fastener having a continuous helical thread, the improvement comprising: forming an essentially void-free block of continuous, non-metallic resin impregnated fibers, by weaving said fibers into an arrangement having a plurality of fibers in first, second and third fi

A method for the production of a fastener having a continuous helical thread, the improvement comprising: forming an essentially void-free block of continuous, non-metallic resin impregnated fibers, by weaving said fibers into an arrangement having a plurality of fibers in first, second and third fiber planes, each plane being perpendicular to the other planes, and impregnating said fibers with a resin; and grinding said block into the shape of a fastener with said continuous helical thread in a manner wherein the fibers in the first plane extend continuously through the fastener and the fibers in the second and third planes extend continuously across the cross-section of the fastener and into the peaks and form the valleys of said helical thread.
