Clueless dealers on Ebay are really ridiculous sometimes:

Anyone have a horizontal adjust screw for the old GPD green mount?

 

One got bent in shipment & the knob is fine if I can get the chrome plated M8 x 50mm threaded part - trying to keep it original if possible. Have looked at various M8 machine screw options on Amazon and eBay and don't want to saw the end off a bolt if I can help it - Thanks!

Hi Rich, 

 

Been a while.  I make tips like that all the time but just for show. I use stainless. That way there is no worry about going through plating and looking ugly or corroding. Sometimes I do tips rounded like that for contact but usually a slight convex surface is enough. 

 

I just took the knob boxes picture and there are some more. I'd need the thread specs to check. Bear in mind that several handfuls or even dozens of knobs is a miniscule collection compared to the variations out there. Most inquiries for a specific item come up empty here. (I get a pm request off and on through the year) wink.gif.  Get thread specs and I'll check, and I'll dome tip it for the cost of shipping - in the unlikely event I match up very close. 

 

Neil

I buy these floweret tops that are made to tight press onto cap bolts (top 3). They come in different sizes and colors at my local ACE. No need to cut a bolt head off.  I then reinforce the top with an auto hose clamp. I haven't seen one fail yet. 

I poked around to find the bottom two, kinda similar but no way to judge thread pitch. 

I hope you find an original.
