John Deere specifies a 5/16 x 2 1/8=E2=80=9D bolt to hold rake teeth on =
their older hay rakes =E2=80=93 a very low tech application. I always =

fine. As far as a blind hole goes, you could always run a bottoming tap =

the bolt to =E2=80=9Cbottom out=E2=80=9D before it really does.

I need a bolt HB815 which is at 5/16 x 1 7/8" long.=20
Rimmer and TRF list this no. under a 2 inch bolt. I'm assuming you can't =
get 1 /78" long bolt anymore. I tried fastenal and Bolt Depot. Not tried =
mcMaster carr.=20
The last time I needed one of these I bought a 2" bolt and cut a bit of =
the end.
I'm just wondering when a blind hole is drilled for a bolt, how much =
dead space is left at the end? Is there some rule of thumb?
