lug nut size??

I want to get the right size socket so I can tighten and torque the Montana lug nuts. I don't have a complete set of sockets that size, but the closest one I found was 22mm. Is that right? It seems a little loose.

Ours are 7/8ths if I recall correctly.

I found the video on the Keystone site and they mention either 7/8" or 13/16", so that narrows it down. I'll grab a couple of sockets and head out and try it.

Thanks,

Jim, Get a 6 to 12" extension also. Makes tightening/torquing a lot easier. Jim

I normally do not like Harbour Freight tools but.... they carry deep well sockets that have a nylon sleeve over the outside to help prevent scarring up aluminum wheels, and like all their stuff, the set is cheap.

Using an extension with a torque wrench will give you an inaccurate torque result.

I use a 7/8 and 4 inch Impact extension. It may be off a little bit. I checked a couple nuts without and with and they both clicked the same, so I doubt if it twisted much

Maybe so but if you keep the extension fairly straight and level it is close enough for what I'm doing.

I got me a 7/8" deep socket and an extension. My wheels and tires were exchanged from the default that Keystone installed to the G614 option. Tiara just swapped my original wheels and tires with the supplier that sells to Keystone; G614s already mounted on the rims. They balanced the tires at a tire dealer before they mounted them at Tiara. I didn't check them myself until I got back to NC, about 850 miles. I set the HF torque click wrench to 120 and every nut clicked without any visible movement. Or anything I could even feel. So my guess is the wheels are at least torqued to 120 ft-lbs.

I'm going to assume I'm good to go and check again in about 1000 miles.

Hate to start a fire here, but it doesn't matter how long the extension is, when torque is applied at one end, the same torque value is present over the entire length of the extension. We are not talking about those fancy impact wrench torque limiter things they use in tire shops, as they are designed to flex at a calibrated torque when used with an impact wrench. The only time a calibration is needed when using a torque wrench is when using a crow foot attachment, which changes the effective length of the lever, which is the torque wrench. This is all basic high school physics.

rohrmann, I'll fan your fire just a little bit since I agree that a single hardened extension will not affect a torque wrench for how we're using it, but it you added enough elbows and extenders to be able to torque your wheels from your driver's seat, then THAT'S when there's a problem. But a single, straight 4" to 6" extension, naw? It's what I use and read somewhere was okay and it sure beats bloody knuckles when I don't use gloves.
