In the construction shown both end portions 5 of the pin are tapered and both end areas 6 of the end portion 2b abut the underlying part 3. The lip can either be curved as shown or it can be flat. The pin instead of being tapered at both end portions as shown can have a flanged head at one end portion. The pin can be used as a hinge pin or for rigidly connecting two members together. |
