Guitar Locking Nut problem

I was screwing down the locks near my machine head on my ibanez S470DX, and when I was screwing it in, not the screw, but the Nut that I screw into got striped. To give you a better idea of what im saying, here is a link of the part I need: http://www.ibanez.com/parts/2004_PARTS/el_guitar/index/index_spec.html once your there click on S / SCA series, and then under S470DX click on ABM. Then click on the part number 2LN1BR43K That is the peice I need, sitting under the 3 nuts! They give the price on this website, but I don't think I can buy anything on ibanez, does anyone know where I can buy this part?

[font=tebuchet ms]Have you tried any shops? Most places will order parts for you.[/font]

Yes, you should be able to order the parts from somewhere ?
Alternatively you might be able to take the part to an engineering workshop and have the stripped thread re- tapped to match bigger screws.
I think the locking device just keeps it in tune, should you accidentaly knock the machine heads, and should play without it ok.
Good Luck

Okay thanks for the feedback guys I'm going to call a music shop soon and see if they can...ill let you guys know how it goes.
