    Default Need Mechanics Advice

    Has anyone cut the wheel lugs down on a 00-06 Sierra/Silverado Half Ton? Being there is 1/2" of non-threaded lug, I don't want to buy 2" long lug nuts. What is the best way to do this?

    Dont do it.
    If you look at the threads their slightly tapered and cut at the end, if you remove this taper you'll have a very hard time threading lugs on and will most likely end up cross threading them and stripping them out. Then you'll need to replace them.
    The length is part of the structural integrity and shouldnt be changed.

    I dont want to cut the threads off, just the 1/2" of untapped narrow tip.

    I'm with the rest of the group, I wouldn't do it but, if you want to go ahead with it, a grinder with a cut- off wheel will probably work the best.

    You are absolutely wrong. In aircraft, bolts are just long enough to get a normal nut and check nut on. Can you think of a more critical application than aircraft? That's just one example.

    OP - Sounds like you want to put on closed lug nuts. Go ahead and cut that end off. I would use an abrasive cutoff wheel. If you happen to nick the threads, just use a thread restore tool to clean them up.

    I would put a lug nut on and cut behind the lug nut giving to a straight cut, Then you have the nut on it to help fix the threads.

    Not a bad idea, but the lugs are hardened, the nuts are not.

    Actually having been an Aircraft Quality Inspector for the Navy for over 22 years, with a Masters Degree in Aviation Structural Engineering, A&P certified mechanic, ASE certified, and worked as an engineer for a Fastener company for a while after retiring from the Navy I'll tell you back that your incorrect on your aircraft description and on your analasis of an automobile wheel stud.
    Any fastener used on aviation equipment is required to have at least 2 threads showing after the last nut, even when using a backing nut (backing nuts are discouraged and whenever possible locking nuts should be used on aviation equipment) this is required so that the nut will not strip off the threads if it's compromised.
    If you check with a manufacturer of quality fasteners ( Like Fastenall for instance) they'll give you the same explanation. This is a standard built into quality fasteners.

    Take the end off of a closed lugnut sometime, there is a space at the end prior to the cap where the nut is not threaded, the endcap just hides this portion, also notice quality capped lunuts normally have a long internal shank.

    What's an internal shank?

    And explain to us all how the un-threaded, and therefore un-stretched, portion of the stud increases strength? In layman's terms...
