Thread: Fitting 16mm LR studs in a trailer hub

[quote=Utemad;942092]Discowhite you appear to have as much protruding as I do. However I imagine you not only drilled the holes yourself but countersunk the heads as well so could do them to whatever depth you like. How much do they protrude the hub surface? they are flush with the end of a steel wheel nut when bolted to a rim.

PhilipA it would be possible to mill the countersink holes deeper but I don't have access to that sort of gear. What did you use to deepen the countersinking holes? in my process, all done in a vice and with a hand drill, i drilled the holes for the studs first, and then countersunk to the right depth with a clearance drill. i sharpened the end of the drill so it was flat and cut more like an end mill. being a machinist by trade i have many ways to skin cats

I figure that since the original LR hub is thinner than the contact depth of the nuts on my trailer hubs I will be fine. If that makes sense.
I'll finish them off this weekend ready for the following weekend's trip.as long as the effective length of the stud is the same length as the nut, that will be enough thread exposed.[/quote]

cheers phil

Ok then. My studs are accurate as I'm just drilling out existing imperial stud holes.
My existing studs were only the 9/16 anyway. Didn't find this out til I fitted the braked hubs. So they were always undersize since new. So what I am fitting should be stronger than existing anyway.

This is the same as I did a few years back, for D1 rims, on a non braked hub.
Since, I have seen in a LR (UK) mag someone, sells longer 16mm studs, which I would use next time.
