    • Over bent and impossible to get onto the axle without beating them on.
Size: 2-3/8" Color: 1 PACK
Review Image by vicki42 vicki42
The bolt itself doesn't look too bad, but they over-bent it on the mandrel. They only measure 2 3/16" between the legs of the bolt. You will either have to put one side in a vise and slide a pipe over the other leg to be able to open them up or just beat them onto the axle with a hammer and hope the plate will drop onto the bolt. Pictures on the item page show 1/2'-20 threads in most photos. These are 12"-13 coarse threads. ... show more
