Both tapered, split and parallel pins are available to join mechanical components together. Sometimes they are used together with a clip of some form to keep them in place.
| Cotter Pin | Most commonly found holding bicycle Pedal Crank Arms on to the Bottom Bracket. |  |
| Clevis Pin | A Clevis (aka Yoke) has many applications where control rods or rigging wires for example have to be connected. The Clevis Pin can be threaded or held in place with a Split Pin and Washer or a Circlip and more specialised clips are also used. |  |
| Taper Pin | Typical uses of these pins are for holding components on to shafts and axles. They are only slightly tapered to enable them to grip tightly and the receiving hole is prepared by use of a Tapered Reamer. |  |
| Split Pin | These are combined with a Washer in everyday use to prevent wheels falling off axles for example. They are used also in conjunction with Slot Nuts or Castellated Nuts to stop them loosening. |  |
| 'R' Clip | Also known variously as a Hitch Pin' or Hairpin Cotter these can be used in similar situations to a Split Pin but they are easier and quicker to apply. |  |
| Circlip | Versions of these clips are either 'sprung' into a groove around the outside of a shaft or a groove around the inside of a hole. Their application or removal is most easily achieved using specialised Circlip Pliers. |  |
