Marshall, A smart idea would have been to take the turnbuckle with you to the hardware store, match the size thread by trying a bolt in the hole, then purchase a number of them for future use. You could then have told us the size. Remember that the turnbuckle comprises a left and right-hand thread. <div class="gmail_quote">On 4 March 2013 12:22, Marshall Gisondi <<a href="mailto:pianotune05@hotmail.com" target="_blank">pianotune05@hotmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div><div dir="ltr"> Hi Everyone, I encountered a Yamaha console today, yeah I had to work a fit someone in. Groupon is great but killing me at the same time :-) Anyway, the two little nuts are missing for the turn buckle/linkage. I thought I'd head to the hardward store tomorrow before I head back to tune it. I had to check for repairs today. It also has several bad cord loops and ones that are disconnected. What size nut will I need or do I need a special one from Yamaha?
