Does the Patrick part have a hole in the shaft into which the cone screw inserts? If not, then you're not supposed to use a stock cone screw, you're supposed to use a tapered tip screw (assuming supplied with the part).
If you use a cone screw on a solid shaft it'll fall out right quickly. Edit: just to explain why that is, a cone screw slides snugly into a tapered hole; it works on shear on that cone. A tapered tip screw screws down into the steel shaft and, while it makes a slight indentation on the shaft, works primarily on friction. This is why, if you're tightening down the [strike]tapered[/strike] correction: CONE screw so damned hard that you're stripping out the Allen head, you're doing it wrong. It needs to be snug, and you use blue Loc-Tite to keep the screw from backing out, not hammering it home. |
