Clevis Bolt

A special bolt used to attach a clevis to a control horn or bell crank so the clevis is free to move. Clevis bolts have a short threaded section separated from the shank of the bolt by a shallow groove. The head of a clevis bolt is slotted so it can be turned with a screwdriver, but the slot is so shallow very little torque can be applied. A thin nut is used on a clevis bolt, and this nut should not be tightened enough to keep the clevis from moving freely on the device to which it is connected.
