Video Transcript for Redline Tires and Wheels 7-122 Review

Today we're going to take a look at the replacement drive-in trailer hub wheel stud. This is a half-inch diameter, two inches long, and a quantity of one. This half-inch stud is designed to replace a damaged wheel stud on your trailer hub. The raised spline portion of this stud is what will be driven or pressed into your trailer hub. The stud is what will go through the bolt hole on your trailer wheel. When used with a wheel lug nut will hold your tire and wheel to your axle. The head of it is stamped as grade eight bolts.

Again, the thread size, the diameter of the thread is a half-inch. There's 20 threads per inch. It does use the standard half-inch by 20 lug nuts. I did happen to pull one of those from our warehouse, just to show you what it looks like. When this on your trailer hub, you put your wheel up on the stud, and then just go ahead and put your lug nut on there.

Tighten it down. Torque it to specs, and your tire and wheel is all connected to your axle. A few measurements on this. The overall length is measured from the bottom of the head to the end of the bolt, two inches. The threaded portion, if we measure just that is 1-1/4 inches. Then the diameter of the spline, that's the portion that gets pressed into the trailer hub.

The diameter on that is 0.61 inches. That should do it for the review on the replacement drive-in trailer hub wheel stud, half-inch diameter, two inches in length, and a quantity of one.

Trailer Hub Wheel Stud - Drive In - 1/2" Diameter x 2" Long - Qty 1 - 7-122

Average Customer Rating:  4.7 out of 5 stars   (66 Customer Reviews)

Replaces a drive-in wheel stud for your trailer hub. 1/2" Diameter bolt.


The Hub Drum matched perfectly with the setup that was there before. I am giving them five stars because everything was how they said, and it matched perfectly. I wish they also add a cotter pin to the kit. That way, you do not have to go and get one to complete the job.


Satisfied with the product & delivery, and good customer service from etrailer throughout the years.


Great replacement wheel studs

Quality product that stands the test of time
Paul B - 07/03/2022


genuinely surprised how difficult it was to find this wheel stud around town. I found it here and bought two just in case. Good quality and identical to the original.


Wasn't sure it was gonna be the right ones but they were and worked perfectly! Wheels are back on and the boat is headed to the water.


These studs are a perfect fit for Lippert 7000 lb axles


I found the exact wheel stud I needed and had it extremely fast. It works great.


Could not find these wheel studs anywhere else. Glad etrailer had them.


After receiving a product that was the wrong size I contacted customer service and ordered these which fit perfect. The customer service at etrailer was a pleasure to deal with, in fact the best company I have ever had the pleasure of dealing with. Thanks so much to the employees for doing such a great job.


Exactly what I was looking for and the only website/company that had the right size and came in quicker than I had expected


Identical size and shape to the old studs in a 12"x2.5" hub for 5200# axle. Hopefully will last longer though.
If you can get the old broken lugs out, these are easy enough to hammer in.


Made some progress on the old trailer finally once I had an original wheel stud to measure from. Made it easy. Thanks!


The product and experience is great!


Just took to long to get


Works as advertised


Fit perfectly on my utility trailer.


Great quality and on time. I always order from etrailer because of their customer support


This was exactly what I required to repair my Wells Cargo utility trailer. The support staff at e-trailer are absolutely great and quick to respond to any of my inquiries. Won't hesitate to use them again.

Great. Replacement studs were exact match to original equipment on my Wells Cargo trailer.
Calvin - 01/31/2020


These were just what I'd been searching for. Reasonably priced. Just disappointing on delivery. Paid for priority mail. They arrived in 13 days not 3. But. I'll order from etrailer again.


Perfect match for replacing the damaged studs on my Dexter trailer hub /brake drum. And etrailer provided the expertise. Saved me time and money.


Simply the best. Best price, best quality and easy to install. Also there are great videos etrailer has for installation of most of their parts. Dont waste your time shopping around. These gutd have the best price. Thanks guys


Great was very easy to locate and order what I needed. They shipped it quickly. The shipping people beat the package up on the way here and lost three items, but people made it good...kudos to their customer service!! Excellent all around.


etrailer had the parts required and was the quickest at delivering the needed parts. Bill with customer service researched the splinted wheel bolt OEM data for me and found what was needed.

Great Customer Service!!!


All the parts I ordered have arrived as promised and worked as they should, I will order from etrailer again as needed.

still working
LINDA B - 02/20/2018


I want to say that I have never been so satisfied with anyone as this particular company. Their customer service reprsentative was knowledgeable. Very patient at helping us
find our special find of a car trailer wheel. We had a misfortune and had to order just
one of the wheels again a few weeks later and they were able to make it very painless to find what we needed again. I would recommend e-trailer to anyone! Great place to shop!!
