Chuck Parts ?

[Alden]

Finally got my first day in the shop after a month on the road. Halfway through drilling a bowl, my block starts wobbling around in the chuck. I got the lathe stopped before it came flying out at my crotch.
Took me a minute to figure out the bolt that tightens up the jaw has stripped out.
My question is, what exactly do you call this bolt, and any idea where I can buy one ?
My chuck is the standard 4 jaw from a Jet BD920N.
The bolt is the square headed thingamajigger you put a key on to tighten the jaws. I'm sure there is one for sale somewhere, just not exactly sure where to start looking.

Now that I just typed that, I realize there are two other jaws and two other bolts somewhere.... I dont recall if Trent Rudat sent them back with the chuck or not

The bolts on that four jaw strip easily. You can get replacement parts directly from Jet, or get a similar one from a machine tool supply.

Thanks Premal. Jets 1-800 number was down all day the day I tried calling. I called Trent and he had a couple in the shop. Sending them to me free of charge, wouldnt even let me pay the priority shipping. What a guy that Trent
