Paul Ash Posted May 23, 2005 Share Posted May 23, 2005 think there 1/2unc. talk to Vulcan engineering, they will supply them in a cap head form, much better than originals. Quote Link to comment Share on other sites More sharing options...

Muttley Posted May 25, 2005 Share Posted May 25, 2005 If I'm not too late, they are 5/16" UNC. I got stainless ones from Stig Fasteners. Warning though, they require a A/F allen key rather than metric, fortunately I actually have a set! Muttley Quote Link to comment Share on other sites More sharing options...

Grizzlee Posted May 28, 2005 Share Posted May 28, 2005 got them from vulcan, nice and cheap! take 5.5mm alen key. Cheers! If you went for stainless ones be careful, they can break easily and usually flush with the hole. Quote Link to comment Share on other sites More sharing options...
