Cotter & Split pins

I always understood a cotter pin to be cylindrical with an angled flat that was either taped into a hole or pulled by a threaded extension thus locking a collar or suchlike onto a shaft that has a flat to receive it.

Also I understood a split pin to be a hairpin shaped device bent out of D shaped wire, poked though a hole in a collar and shaft with the ends bent apart to prevent it coming out.

I now see what I understand to be split pins widely advertised as cotter pins.

What's what, who's who, why and wherefor ?????????

I'm certain Capricorn One was true and filmed in a hanger in Arizona, if they can't get 3 wires across America carrying more voltage than can be obtained from 7 D cells then how did they get a man on the moon ?

Just been reading a reply from a guy in the states where he has to take his pickup and trailer to collect some steel bars, it does 7 mpg. SEVEN mpg ???????? F=FCck me, my mates Volvo does more than that with 44 tonne on it's arse.

Andrew, I'm with you 100% on this. Reading the internet 'expert on everything', Wikipedia gives this insight:

Cotter pin can mean: In USA usage: A split pin, a metal fastener with two tines that are bent during installation used to fasten metal together, like with a staple or rivet Hairpin cotter pin, more commonly known as an "R-clip" Bowtie cotter pin, a vibration proof type of R-clip that is shaped like a bowtie Circle cotter, a ring shaped cotter pin In British usage: A cotter, in mechanical engineering a pin or wedge passing through a hole to fix parts tightly together This usage difference is often a cause of confusion when companies of both countries work together.

I guess that explains it, those pesky Americans confusing the issue again ;-) Martin

Remember that the USA can't measure things and that their pints and gallons lose a lot in the translation.
