The present disclosure includes a part hold-down assembly for retaining a part. The part hold-down assembly includes an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The upper collar has a first end, the first end having an annular ledge. The lower collar has a second end, the second end having an annular ledge. The resilient biasing member includes a first end and a second end, the first coil end configured to engage with the annular ledge of the upper collar and the second coil end configure to engage with the second annular ledge of the lower collar. A stabilization tube may extend within a central aperture of the resilient biasing member, the stabilization tube reducing or eliminating movement of the resilient biasing member in a direction that is not parallel with the direction of the central axis of the part hold-down assembly.
