Hi,

I am about to replace a SS wedge bolt but have not placed a glue-in before. Using Sika Anchorfix and 3/8 SS rod stock. Considering using 1/2 threaded rod stock now, too.

Looking at this thread,

http://www.rockclimbing.com/forum/Community_C10/Campground_F32/You_are_not_wanted_here._P2217755-512

The guy advises drilling 1/8 bigger than the threaded stock. Anchorfix's spec data advises drilling 1/16 bigger. So... What gives?

A few posts later they're talking about "bro sex" and cow tipping. By the end of the page it's lepers and prostitutes. And in between were enough spelling errors to give Webster an aneurism. Is that really who you want to get advice from?

With threaded rod 1/16" bigger is plenty since you have all of the volume between the threads for the glue to fill as well. You would probably be okay drilling a full 1/8" bigger, but why not just go with what the manufacturer recommends?
