Also called
- n. Cotters were used in place of the nut and thread on a bolt before the cutting of threads was easy and cheap, and are still useful where the thread would be liable to injury. A wedge-shaped or tapered flat pin (cotter) is driven into a slot cut near the end of the bolt or stud, drawing up the bolt. A similar device is used to secure nuts on bolts from being shaken off. A hole is drilled through the bolt, at right angles to its axis, beyond the nut, and through this hole a taper pin is driven. The cotter in this case is often split at its smaller end, and if the two parts are spread it cannot of itself work out. In small work the cotter is made of half-round wire, bent double on itself, with an eye at the bend, so that when it is in place and the ends are spread, it cannot slip out either way. The hole can therefore be straight or cylindrical and not tapering, and the cotter has no wedging action in this form. Cotters are much used in motorcar construction.
