A clutch fastener is provided for securely receiving pins, shafts, and the like. The clutch fastener includes a housing and a coil spring disposed within a central chamber contained in the housing. The chamber originates near the top surface of the housing and extends through the bottom surface. The bottom surface is countersunk to provide for easy insertion of the shaft. The chamber is sized such that it has a larger diameter than the shaft to be retained. The shaft is inserted into the chamber and retained by frictional forces generated against the coil spring. The clutch fastener may allow the user to selectively increase the tension placed on the shaft via a locking mechanism. The clutch fastener may also be provided with a second spring disposed within the chamber in order to limit the degree of compression of the first spring. Various designs are also disclosed for the spring stock from which the coil spring is formed.
