    Sorry guys but I'm pretty frustrated. I need a few 2" long 7/16 - 20 fine thread bolts that are fully threaded. Grade 8 or higher. Everywhere seems to have them but not threaded all the way. Any leads?

    Gracias!

    I don't think I have ever seen any that fit that description. Generally, anything longer than inch or inch and a half has a shoulder, except in lower grade bolts with course threads.

    I can't have a nut on both ends. One has to have a head..:) Theyre all over the place in bulk. Surprised they're not more popular!

    Just out of curiousity, what are you using this bolt for ? Sounds like some special application.

    I have buick drums with 40 ford hubs on the outside. The hubs are threaded and the wheel studs (which are just bolts) pass through the drum, thread through the hub and then become the stud for the wheels. I have 1.5" bolts on there now and with them cranked down they sit just barely flush with the lug nuts. I have a need to run 1/4" spacers and there's no way. 2" bolts will give me the 1/4" I need plus a little more..

    Oh. Are you sure those aren't 1/2 inch bolts ? We have the same setup and the bolts are 1/2 inchers.

    Almost all cap screws are threaded twice the diameter plus 1/2". You are not going to find 7/16-20 all thread rod in grade 8, can in 4140HT. $3.75 is pretty reasonable considering they are holding your wheels on I would think.

    the torsion bar adjusting bolts on some of my old sprint cars were 7/16 fine grade 8 about 2-2 1/2 long,threaded all the way down.check with speedway motors or another place that supplys sprint car parts.are you sure you dont need 1/2"/

    You might also check with Moser axles, they carry them in 3 inch threaded all the way because they use them on their race axles. If you are running hubcaps the extra inch will be hidden, or you could chop off what you don't need with a hacksaw. Just thought they might be cheaper from them.

  18. Dreddy,
    Do you have a fastenol there?

    When I need drive studs for a threaded flange I usually have to use an allen bolt. Probably not what you are after but they seem to be the easiest to find fully threaded.

    Anyway fastenol is a good place to look. They may have an online store or if they don't I would be willing to call them here if you don't have one near you.

    Have you tried the racing supply stores to see if they have wheels studs that size and length?

    Thats because its a set screw you need :D set screws are threaded all the way whereas bolts have a shank.

    I called Moser for you, he says they only carry 1/2 inch. I forgot about what Benno said, allen heads are available like that and you can get grade 8's too. Just a little dab of Locktite red on just the portion that threads into the hub and you should be good to go.

    All thread or studding as we in england know it is very low quality, it has no place on a car in my opinion.

    Are you sure you need "grade 8 or higher"?
    I get that sometimes we get an idea that keeps us going down the same dead end street but I just want to mention that I've had my share of fun with these drums and have never used anything other than standard ungraded hardware. And my 5000lb+ Electra still goes down the road every day with stock studs.
    I think you might consider making this a little easier on yourself.

  25. Langy...on this side of the pond a "set screw" is a headless screw.

    I called a few places, like Fastenal and Specialty Fasteners, and no one carries them. I think you just need to bite the bullet and spend the $40 to buy the 10 you need from that place you found them at. Sometimes that is just the easiest way to solve a problem, rather than running around all over the place.

    Those ones you pictured even have the bullet end on them which will make getting lug nuts on easier.
