Title: RMS cap bolt size
Post by: Raindem on May 20, 2017, 01:04:54 PM
What is the correct socket for the RMS cap bolt on a 440?  It's not a standard hex head.  It looks like a Torx head but none of my torx sockets fit it.   I have a spline socket set that goes down to 3/8" but that doesn't fit either.  5/16" spline?

Thanks

Curt

Thanks Nacho.  A 12 point star, that's not the same as a "spline" socket?

Dunno, I just posted how I know it and 440source call it the same

I believe they are the same.  My 3/8" spline socket wouldn't fit in the recess those bolts are sunk into.  So I took it to the grinder and made a thin-walled socket out of it.  That did the trick.  They seemed to fit the bolt OK and I managed to get both out without stripping them.
