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.

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


This was exactly what I was needing. It took me a little while to find it since this was not offered anywhere else, at least that I could find. I installed this on my 2022 Vengeance Rogue 32V camper. It was a perfect fit. It shipped in & arrive at may house in more than a reasonable time but who am I kidding. etrailer has always taken care of my trailer needs over the years. Dont overthink it. etrailer has your back.


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.



Stud still works as intended. It hasnt broke or come loose in the brake drum. Good product


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



Great never had any issues with the wheel studs


These were a perfect fit for my 5th wheel and Kimberly did an excellent job helping me find the correct part! Great customer service!


Exactly what I needed!


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.


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.


Great replacement wheel studs

Quality product that stands the test of time


Only place I could find this stud.


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


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.



No problems over the last 8k kms


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


They are the size I needed, I hope I never have to use them.


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!!!


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


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!!


I’m writing to praise Braden E in Customer Service. Braden spent a great deal of time with me in researching exactly what hubs I needed for a very old axle. At one point I asked Braden if he was the owner. Why? Because I was struck by his attention to my needs, his tenacity and persistence in getting things right. He is truly an asset to the company. I think Braden is a rare breed these days. I’ll be a repeat customer because of my interaction with him.


10/27/20 Just got the studs. The .61 diameter spline fit perfectly. Glad you recommended getting two instead of one. Now I can fix the trailer hub and not worry about it breaking under a load.


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

still working


Fit perfectly! Customer service was Excellent as always.


I received these as replacements due to damage during shipping. Etrailer was terrific in handling this issue.


Trailer lug nuts were the perfect fit and shipped quick!


Lug studs fit perfectly. Used to replace broken wheel studs on my 44 ft Haulmark race car trailer. Great price and quality.


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


Well, I assume it’s a good product unfortunately this wheel stud is not a replacement for a 6109 SJ stud as indicated on the web sight so it will be going back. Kathy in Customer service was great working with to resolve the problem.
