I'm looking for a source of what I know as 'aircraft pins'. This is a pin with two ball detents sticking out at one end, which are held in place by a sprung central (inner) rod. When the inner rod is pushed axially against the spring it allows the balls to move and the pin can be withdrawn from whatever hole it is inserted into.

Is there another name for these, and if so what is it?

Obviously they would not be a desperately difficult thing to make, but I've always assumed that they are standards parts, so does anyone know where they can be purchased from in small numbers? Ideally, a UK source, but US is also 'doable'.

Thanks

Nick.

What size pins do you need? I could possibly get you some about 8mm dia x 40mm long approximately, can get you exact measurements tomorrow.

Racers call them pip pins. Carr Lane has them as stock items.

McMaster has a few styles, not exactly what you describe, but workable.

Your local marine store (e.g. West Marine) also probably carries them.

I think the technical term is "ball detent pin". PIP is the common acronym for "push into place".

Thats what they were called at the place I worked at 30+ years ago.
They were the kind with a push in the rear to let the balls retract. (that sounds nasty)

Here is a thread from a year back. I remember it, because a few years ago I experimented with making a few types of latching pins. I included photos of a single ball type I devised, it was easy to machine, uses a cut-down bolt for a spindle, no riveting required etc.

No, I think he was asking about the ball detent pins.

But for sheetmetal fab and trial assembly - Clecos rock!
