There’s more than one way to spell lynch (‘linch’) and more than two designs of pin. Some are more secure and friendlier to use than others…

What springs to mind when you think of the humble lynch pin? A handy way to secure bits of linkage or small trailer tailgates; a thing too easily put down and lost; a snaptrap for unwary fingers? It’s all of those and more, usually working without complaint even under unreasonable loads.
