1/4 - 28 fine thread. I use a quality Allen head bolt there.
Jeff
thanks for the reply
are the heads on the standard ones 1/4" as well?
It's an Allen bolt. Takes a hex wrench.
Jeff
OEM bolts were 1/4-28 with 1/4 12 point head.
Correct. I was unable to locate 1/4 " x 12 point bolts, so I went with Allen bolts instead.
