Wheel Studs
 

Have Moser axles 5/8" 18 TPI RH knurl .685, pressed in studs. Need longer studs . Moser only offers 2 1/2" under the head length. Need 3 1/4". Looked on Summit / Jegs , ARP, others. Nothing in .685 knurl. Any racers run in to this and solved it, short of replacing the axles???

Re: Wheel Studs
 

Moroso has a 5/8 stud 3" # 46240 with a .672 knurl,or a 3" 1/2 stud with a .685 knurl #46190.Also M-W has a 4" drive stud kit in 5/8,but the hole in the axle is too big to tap at .685.The thread dia.is .625 for the 5/8 screw in stud. gsa612

Re: Wheel Studs
 

I will look at those part numbers, thks.

Re: Wheel Studs
 

46190. Is shown as a 1/2" 20 stud? I Need 5/8".

These won't work?

Re: Wheel Studs
 

Looks like these may work,the only thing is there a coarse thread (11) and yours are 18.Just have to get new nuts. gsa612

Re: Wheel Studs
 

What type of rear wheel are you running?. gsa612

Re: Wheel Studs
 

Bogarts came on the car. I purchased some Weld Pro Stars for a set of spare rim/tires. The Welds have a 1/2" thicker hub.
The 11 to 18 threads per inch change, could be the solution, need to understand how it effects the rim, and stud torque.

Re: Wheel Studs
 

not sure if this will work but take a look at a Dorman 610-418 or GM 15725054 stud --these are used on GM duallies rear ends

Re: Wheel Studs
 

When you put the bogarts on with the 5/8 studs that you have,is there a lot of space between the wheel stud hole and the stud.Does the wheel move back and forth?.The od.of the 5/8 stud is .625 ,and the hole if you were using a shank nut would be .685.The only nut that seems to be available for the 5/8 course stud is flat on the back were it presses against the wheel.The cars that I've seen using 5/8 studs are using a M-W stud kit,that has a 4" stud that threads in the axle flange.then there is about a 2". 685.bare shank in the center
that goes thru the wheel and is tight inside the hole.It then has a threaded portion that you put a spacer and nut on.The Jegs 5/8 course stud might be better suited for a circle track car with a steel wheel,were you would use a beveled nut to center it in the hole.See what you come up with and keep us posted. gsa612

Re: Wheel Studs
 

Both the Dorman # unfortunately are .657 knurl diameter. The Moser are .685.

Re: Wheel Studs
 

look at Speedway motors part #91005960--its a 5/8-11----- 4 inches long with a .685 knurled --you will haft change lug nuts but this should solve your problem --$13.99 set of 5--- now all you have to do is get the appropriate nuts--FED 387

Re: Wheel Studs
 

Or send the axles back and have them drilled and taped for the big studs.

Re: Wheel Studs
 

What Larry said...if you roam the pits you’ll note Stock Eliminator is about the only class you’ll even see many 1/2 inch studs. My car has a good 9 inch setup but surprisingly was built using the smaller studs, and after breaking two studs it was hard to even find some last weekend (thanks to Mike McMahan, the Valdosta r/u, for the loaners). Moser sells the whole 5/8 stud kit for $80 so is by far the way to go. Losing a rear slick is never a pretty picture.

Re: Wheel Studs
 

Thanks for everyone's replys. I thinking I'm going to go the drill and tap the axles route . I want to keep the 5/8" 18TPI .
When ordering new axles, thread in studs is really the best way to go in my opinion.

Re: Wheel Studs
 

The moser #8080 kit is the answer,same deal as the M-W but cheaper.It comes with 2 sets of spacers,long ones for the bogarts,short for the thicker welds.If you look at the unthreaded center the OD is larger so it fits in the wheel hole.They list it as 3'',but it should work. gsa612

Re: Wheel Studs
 

I hope I am wrong, but I think I have read somewhere that race axles can be very hard to drill and tap.

Re: Wheel Studs
 

I don't know about Moser but Strange will drill and tap their axles from 1/2 to 5/8 as long as the have not been welded on, Studs tacked etc. I had mine done by Strange about ten years ago and the cost was minimal. They fit the wheels perfectly when I got them back. Turn around was very quick as well.

Re: Wheel Studs
 

Moser offers that service as well.

Re: Wheel Studs
 

Just asking , but if 5/8 is .625" and your axles have a .685 knurl , how do you tap them for a 5/8 stud ?

Re: Wheel Studs
 

Quite a difference between 1/2 & 5/8,
Proof load for grade 2-5-8 for 1/2 stud = 8800-13600-19200
For 5/8 stud = 14100-21800-30700, a good 30% + - stronger across the board
I always heard not to use the grade 8 because it's to hard & brittle, use grade 5. Not sure what they use from Strange or Moser.

Re: Wheel Studs
 

He's going to need 10 new holes indexed,drilled and tapped.The current knurled stud hole is bigger than a 5/8 threaded stud.Hope it don't have 1" lightening holes between the existing holes then your SOL. gsa612

Re: Wheel Studs
 

Post # 2 lol...gsa612

Re: Wheel Studs
 

My axles were drilled for both 1/2 and 5/8 screw in studs. The axle flange still isn’t the weakest link.

Re: Wheel Studs
 

Contact Mark Williams.
They solved my moser problems that moser just could not.
Many length 5/8 studs, washers, lugs and associated parts.

Re: Wheel Studs
 

Grade 8 is stronger across the board, including tensile. My Moser axles are tapped for 5/8" x 18 thread bolts, so I just buy long enough bolts. If the wheel hole is much bigger than 5/8", you could get sleeves or find studs with larger unthreaded areas. People who think grade 5 is better, why does ARP make bolts and lug nuts?

Re: Wheel Studs
 

Something like, the harder it gets the more brittle it becomes.
