Abstract
A pushnut fastener for use in conjunction with a cylindrical shaft having a pair of opposed flat surfaces extending therealong. The pushnut has an opening that complements the shape of the shaft and includes arcuate blades that are, in assembly, biased in contact with the arcuate surfaces of the shaft and straight blades that are biased in contact with the flat surfaces of the shaft. In a relaxed condition, the straight blades are generally parallel with the horizontally disposed base of the nut and the arcuate shaped blades are set at an angle of about 45.degree. with the base.
