Abstract
An improved cylindrical interference fit for joining and fastening synthetic polymeric material connecting members comprises a smooth surfaced shaft and a complementary internally ridged recess. The shaft, during insertion into the recess, shears away the tips of two spaced longitudinal ridges positioned within an 180.degree. angular segment of the recess and bindingly engages the sheared tips and a portion of the internal surface of the recess thereby forming a three-point interference fit, interlocking joint between the joined members.
