I'm in the process of replacing the brakes on this tractor and 2 of the 7/16" by 2.5" studs (6 per side) have the fine thread portion of the stud stripped. The part number (I believe) is 88463S7 and I'm unable to find these new on the internet. Does anyone know where I can find these? The other end of the 2.5" stud is a 7/16" coarse thread. If I need to fabricate these what strength of 7/16" steel rod should I use?

Thank You, Bill.

Bill send me an email and I will send you pictures. I found two right on top of a bucket of bolts and nuts. There is some wear on these but I can thread nuts onto them.

Sent you an email with pictures.

I have some used ones.

Hello HCooke, Thank you for your response! I'm sure glad I checked into this forum. Please email a picture of the studs and how much you want for them.
Thanks again - Bill.

Give me some time to look for them. It has been a while but I will look.

Try this link to Summit Racing. Studs are available through several suppliers. You won't find many of the old Ford fastener parts anymore by their part number. Studs are designed with a nominal thread size, 7/16" in this case, and one end is a Fine Thread (NF) and the other end is a coarse Thread (NC). The NC/Coarse end always fastens into a cast iron part and the NF/Fine end always accepts the Hex Nut. Studs are a stronger fastener than a bolt. If you stripped one end of your stud, did you accidentally try to insert it backwards with the wrong end? You may want to check the axle housing as that is essential it has the right TPI size. Do you have a 7/16-14 Tap in case you need to chase the housing.Studs are easily replaceable, axle housings not so much. Summit supplies Dorman products. The 7/16 x 2-1/2 Stud is listed at $26 for pack of 10.

• 7/16 STUD

Hello Tool Pro,
Thank you for your response! I checked out the Summit Racing link and this is exactly what I need (including the Grade 8 steel). What happened was when I was taking the axel apart on one side two of the studs came out with the nut as opposed to the nuts coming off of the studs. Then in the shop I removed the fine thread nut from the stud and discovered the threads were badly worn. The coarse threads that go into the rear axle housing looked OK on the 2 studs that came out. I'll see if I can run a 7/16-14 Tap into the hub to be sure the threads are OK for the 2 studs I removed. This ends several hours of internet searching. I'll be keeping the Summit Racing link as well as Dorman (the manufacturer of the studs).
Thanks Again, Bill.

If you run a tap into axle housing might want to check if they are blind holes, I can't remember, but studs are often used in blind holes so get a mini-mag and pencil and look first. Best to use a bottoming tap if so -don't want to snap off the tap, have had customers do that B4 too. If you need a tap I can send you one - I have plenty. Sounds like you are on top of the game so good luck.
