Video Transcript for Kodiak Tires and Wheels K12WB2 Review

Today we're going to look at the Kodiak replacement drive-in trailer hub wheel stud. It's a half-inch in diameter and two inches in length, and it's a quantity of one. Now, this half-inch stud is designed to replace a damage wheel stud on your trailer hub. The raised spline portion right down here of the stud is what will be driven or pressed in to your trailer hub. This 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. These are stamped as a grade-eight bolt.

The thread end size, again, is half-inches by 20 threads per inch, and uses a standard half-inch by 20 lug nut. I happened to pull one of those lug nuts like this one right here, and you can see they just screw right on to the end once you put your wheel and tire assembly on, you just put your lug nuts on and torque them to the correct specs. Just to give you the measurements the overall length which you measure from the bottom of the head to the very end of the bolt, you can see is right at two inches. The threaded portion is right at about one-and-a-half inches long. Then, the spline diameter is going to be .54 inches. That should do it for the review on the Kodiak replacement drive-in trailer hub wheel stud, half-inch diameter by two inches in length for a quantity of one..

  • How Long Do My Lug Studs Need to be on Dexter 2200-lbs Axles
    I'll start by saying that without knowing which hubs are on those axles, it's tough to know exactly which lug studs are on them, but I was able to research and determine that the studs are normally 1.8" long. Taking this into consideration, you're going to need studs that are at least 2.3" long to make up for the added space between the hub face and wheels. The Kodiak Wheel Bolts # K12WB2 are only 2" long, so these are not going to be sufficiently long enough. I recommend using the...

  • Recommended Replacement Wheel Studs for Hub with 5 Studs
    For your wheel studs, I believe you will want the Kodiak Wheel Bolt - 1/2" Diameter x 2" Long # K12WB2. Another close option but with a wider spline is the Trailer Hub Wheel Stud - Drive In - 1/2" Diameter x 2" Long - Qty 1 # 7-122. These are the closest options to your measurements for your hub. I've attached photos of these measurements for you to compare.

  • Wheel Stud that is Longer Than K12WB2 with Same Diameter
    We have the part # DX98FR which is 1/2 inch longer than the # K12WB2 that you referenced and is same 1/2 inch diameter.

  • Recommended Replacement Wheel Stud For a 2016 Kaufman 3 Car Wedge Trailer With 7,000 lb Axle
    We do have the replacement part you need. I reached out to Kaufman to get the specific dimension of your wheel stud for your 2016 3 car wedge with 7,000 lb axle. They told me that it is a 1/2 inch x 1.99 with 20 threads per inch. The replacement part I recommend is the Kodiak Wheel Bolt # K12WB2. If you lost the Lug when the stud broke, you will want, # CE11051, or for an enclosed chrome lug # 12CLN.

  • Replacement Wheel Stud for 2006 Boat Trailer with Disc Brakes
    We do not have the obscure replacement stud you are seeking. The Kodiak Wheel Bolt - 1/2" Diameter x 2" Long # K12WB2 will meet your measurements with the exception of spline and base length, so it will fit but won't be quite as strong as your previous wheel stud. This is the closest fit we carry.

  • Replacement Wheel Stud Needed For 2012 Karavan Snowmobile Trailer
    I can get you the replacement wheel stud. If you need a drive in 1/2 inch stud, we have the Kodiak Wheel Bolt - 1/2" Diameter x 2" Long, # K12WB2. If you have the screw in 1/2 inch stud, we have the Replacement Wheel Stud, Screw-In, 1/2" x 2", # 25-53. If you need the replacement 1/2 inch lug nut, I suggest # CE11051. I've attached a link to our page on wheel studs. If you have more specific measurements to fit, let me know and I'd be happy to help.

  • Can Trailer Hub with Screw-In Studs Be Converted to Accept Drive-In Studs
    I do not recommend trying to convert your existing trailer hubs so that they will except drive-in studs like the Kodiak # K12WB2 that you referenced. This is going to require some modification to the hub (such as drilling like you mentioned) that will void its warranty and could also affect its integrity. Your best option at this point is to simply replace the hub altogether. If you can tell me the inner and outer bearing that your existing hub uses along with its bolt pattern and capacity,...

  • Replacement 1/2-20 Wheel Stud For Reliable 1206 Trailer Hub
    In order to match up the wheel studs for your Reliable 1206 hub, we'll need to know the full dimensions of the wheel stud you're replacing. In addition to the total length of the stud and its diameter and thread pitch, we'll also need to know the length of the threaded area of the stud, the length of the splined area and the diameter of the portion that's driven into the hub. In the case of the Kodiak # K12WB2 wheel stud you mentioned, the diameter of the splined area (portion driven...

  • Replacement Wheel Studs with Longer Threaded Dimension
    To get the wheel stud replacements you need, you will need to take some measurements using a digital caliper like # PTW80157. You will need to give me the thread diameter, spline length, base length, spline diameter. From there we can get the thread length and stud length that will make the wheel studs compatible with your application. I've attached a photo to assist.

  • Replacement 2" x 1/2" Wheel Stud Needed for a T52 Axle
    If the Kodiak Wheel Bolt # K12WB2 is close but requires slightly different (larger) measurements then you may be needing the Trailer Hub Wheel Stud # 7-122. I am attaching photos of both for you to compare. The Redline photo doesn't have the "F" measurement but you would find that by simply subtracting "D" from "B". This means the "F" measurement would be 1.26" or just over 1-1/4".

  • Replacement Wheel Studs and Lug Nuts for a 2011 Crossroads Cruiser 5th Wheel Trailer
    The first thing to check is if the hubs have studs that are driven in or that are threaded in. Stud # K12WB2 is a drive-in type so if you have ones that thread in it would not work. If they are drive-in then you will want to check the picture I have included that shows all the measurements to determine if they will fit properly in the hub. This stud takes a 1/2"-20 lug nut such as # CE11051. This is an open-ended lug nut so the additional length of the studs would not be a problem....

  • Replacement Wheel Bolt or Replacement Hub for Haul Master 90145 Utility Trailer
    For your utility trailer, I recommend pulling one of the studs and measuring for fit. I've linked the picture measuring the Kodiak Wheel Bolt - 1/2" Diameter x 2" Long # K12WB2 for reference. You will need to use a digital caliper like # PTW80157 to get the precise measurements. Your other option is to pull your hub and get the bearing numbers and seal number from your hub for a replacement hub. If you can't find the numbers printed on the face of your bearing you can use that digital...

  • Replacement Studs for Trailer Hub that are 2 inch Long and .54 inch Spline Diameter
    Based on the dimensions of your old studs the part # K12WB2 that you referenced is exactly what you'd need. The .02 inch diameter difference you mentioned for the splines ensures that the stud fits tightly. I attached a review video for this stud for you to check out as well.

  • Replacement Wheel Studs For 2013 Puma Canyon Cat Travel Trailer
    We have replacement studs and hubs. You'll need to take some measurements of the lug stud like the dimensions on the attached picture of the Kodiak Wheel Bolt - 1/2" Diameter x 2" Long # K12WB2. This will help us to get you the right one. If you need the replacement hub, we will need measurements or bearing numbers. I've attached an article to help.

  • 2 inch Long Wheel Stud Recommendation for Boat Trailer that is 1/2 inch in Diameter
    I believe what you are looking for is our part # K12WB2. This has a thread diameter of 1/2 inch, a spline diameter of .54 inch (I know you said .56), and is overall 2 inches. This is our closest option and is a very standard stud seen for trailer hubs so I'd be surprised if this wasn't exactly what you need.

  • 2 Inch Long Trailer Hub Stud Recommendation with 5/8 inch Diameter Spline

  • Replacement 1/2 Inch Trailer Wheel Studs 1-3/4 Inches Long
    The best replacement wheel stud we have to suit your needs is the Kodiak Wheel Bolt part # K12WB2 which is a tad longer but that won't be an issue. The most important metric to match are the bolt diameter and spline diameter/length and these appear to be pretty much an exact match. If you need lug nuts as well we have part # X1023R and part # 12CLN-L.

  • Availability of Replacement Wheel Studs for AL-KO 8490 Drum
    The studs on your AL-KO drum should have a 1/2" diameter like the Kodiak # K12WB2 but you will need to filter through the attached link of wheel bolts to find the one that matches your stud length. These are filtered by total length but you can click on each individual page to see the length of the threaded portion to match your application.

    I would love to help but in order to make sure we get the exact wheel stud you need for your 2013 Ice Castle Trailer we are going to need a bit more precise measurements. In order to find these precise measurements you will need a digital caliper like part # PTW80157. I have attached a photo of the measurements I will need to make sure you get the correct replacement wheel stud. Judging from the photo you have attached it should be either part # 7-223 for 9/16" diameter or part # K12WB2...

I also linked our page for hub/drum assemblies in case you prefer to simple replace the bad hub. Be sure to confirm your wheel bolt pattern (there are several 5-stud bolt patterns - please...
