How to measure wheel studs?

[LS1_C10]

Im sure at least one out of five people come across this problem, but Google isnt helping. I need new studs on the front axle. They gotta be longer. I can get one off the truck with no problem, but the parts places can only look up by make/model/year and Jegs/Summit sells by exact measurements. What do I do when I have the stud in my hand to know what to buy?
I called Summit and they have longer studs. I just dont know which ones I need. "Wheel Studs, Press-In, 1/2-20 in. x 3 in. Long, .615 in. Diameter Knurl, Set of 5" doesnt really mean much to me.

Id take one of the studs to the store and find a lug that will fit it

Id rather not eyeball measure something that has that many digits after the decimal. Its inviting problems.
Plus I need longer studs by at least 1/2". No one local has them. They HAVE to be ordered Summit or Jegs, which requires precise measurments.

i use a caliper to measure with// harbor frieght has them with electrronic display for readout, avery handy tool to have at quite reasonable prices

Yup I'd take my calipers,one of the old studs and one of the old lug nuts.

Just have the parts store look up the origional stud for your truck and look at the specs for it. Then get one how ever much longer you need.
O'Reilly's web site lists the specs. This is for a 74 K10 with a 350:

Just select your truck search for wheel stud. And BTW a decent parts store should be able to do this for you, but I know those are becoming few and far between.

I tried that too. Unfortunately, the studs from the parts store dont have any info on them, just the application. So I would still need to measure, lol.

Harbor freight does have some decent caliper prices.

I may be confused here but are you trying to put half inch studs where a 7/16" stud was originally?

I thought that number referred to the twist for the lug nuts. Am I completely wrong? cus when I search 1/2 20 on summit, I get lug nut results.

[smbrouss70]

The numbers that you are referring to is the stud diameter and the thread pitch in teeth per inch. If you originally had a 7/16"-20 RH thread wheel stud, then you should go back with a 7/16"-20 RH thread wheel stud. This should be more of what you are looking for...

Wheel Studs

[LS1_C10]

I saw those too but I was under the assumption that the shoulder was longer on mine.

[smbrouss70]

You're right, the front studs on your truck should have a longer shoulder. The only option I see without going to a smaller knurl diameter is this one. The knurl is slightly larger and you may have to drill out the hubs a hair, but more than likely they'll press in with just a little more force.

[LS1_C10]

Those seem to be exact except for the knurl. Will it be close enough to work?

[smbrouss70]

There is a difference of 15 thousandths of an inch between the two, with the new one being the larger one. I would think that they would press-in fine, with just a little more resistance than a stock replacement stud.

[LS1_C10]

Sounds like a job for WD40! lol. Ok. you made up my mind!

[Shon]

Did you ever purchase and install longer studs? I want longer ones too and hard to find the right ones, as you have noted....

Ever have one of those months where you gotta sell the wheels n tires on the truck to afford to install the new ones? Lol. They are sitting in my Cart on summitracing.com.


The guy who posted the Dorman info ultimately saved my butt. Goto https://www.dormanproducts.com/catal...ec10_Part2.pdf and find your application, then goto summit and type in the knurl and the turn. Like 7/16 20 .565 or whatever it is
