SPLIT PINS

V. Ryan © 2004 - 2008

 

A large range of fittings for wheels, shafts and screw threads are available. Most fittings are temporary in that they can be tightened and untightened when required. The fitting below is strong, safe and low cost.

Split pins are very common as they are easy to use and effective. Often they are found on self-assembly trolleys, light wheel barrows, lawn mowers and similar items. They are usually made from ‘soft’ steel or aluminium and they come in a range of sizes.
 

The shaft/axle is normally drilled so that the split pin can drop through or can be ‘tapped’ through with a hammer. The legs of the split pin are then bent to form an angle, holding the split pin and wheel in place.
A washer can be used to reduce friction between the split pin and the wheel. Split pins are strong but after time they can wear and break.
