A mechanism for automatically inserting a threaded rod 1 into a threaded socket 2 in a plate 3 includes a loading member 4 formed with a recess 5 arranged to contain the rod 1 and a spring-loaded plunger 6 which biases the rod 1 towards the plate 3. When the rod 1 is rotated by a screwdriver 7 inserted into the upper end of the socket 2, the rod 1 will be drawn up into the socket 2. The rod 1 may be part of a printer print hammer assembly. The loading member 4 includes a chamber 11 formed at its upper end with an end wall 12 through which extends a hole 13. The plunger 6 has a body portion 14 located in the hole 13 and a flange 15 located in the chamber 11. A spring 16 extends between the flange 15 and a stopper 17, closing the lower end of the chamber 11.
