A fastener component comprises a field of loop-engaging elements each secured to a support. At least one of the elements has a molded, cantilever stem secured to the support at a base, projecting from the base at an acute angle to the support substantially linearly along a lengthwise axis to the region of a distal tip. The length of the projection upon the support of the portion of the cantilever stem beyond the base is between about 0.5 and 2.0 times the width of the base of the element, and the length of the projection upon the support of the portion of the stem between the tip and the point of its greatest spacing from the support is less than about 0.25 times the width of the base. The structure of the element can be useful for engaging very fine fibers that have low loft such as are found in inexpensive non-woven materials, due to minuscule motions of the head of the fastener element during engagement. Molds and methods for forming such fastener components are also disclosed. |
