Video Transcript for Redline Tires and Wheels 7-257 Review

Today we're going to take a look at the replacement drive-in trailer hub wheel stud. This is a 9/16 diameter, 2-1/2" in length, and a quantity of one. This 9/16 stud is designed to replace a damaged wheel stud on your trailer hub. The raised spline portion right here on the stud is what will be driven or pressed into your trailer hub. This stud is what will go through the bolt hole on your trailer wheel, and when used with a wheel lug nut will hold your tire and wheel to your axle. The bolt on the top of the head is stamped as a grade 8 bolt. Again, the thread size, 9/16 in diameter, 18 threads per inch, and it uses a standard 9/16 by 18 lug nut to go onto this. That size lug is usually used on 16" and larger wheels.

The overall length, we're going to measure, is going to be measured from the bottom of the head to the very end of the bolt. That's your 2-1/2" in length. The threaded length, we'll just measure the threaded portion, is going to be right at 1-1/2", and then the spline diameter, the portion that gets pressed into the trailer hub, the diameter of that splines is 11/16". That should do it for the review on the replacement drive-in trailer hub wheel stud, 9/16 diameter, 2-1/2" in length, and a quantity of one.

Ask the Experts about this Redline Accessories and Parts

  • Can Wheel Studs on Trailer Axle Be Replaced
    Yes, the studs on trailer hubs are replaceable. You'd need to know the diameter of the stud you'd be replacing as well as the length. I attached a link to a page that has all of the studs we offer. The most popular stud replacement we offer is the part # K12WB2 which is 2 inches long and 1/2 inch in diameter.

  • 9/16 Inch Lug Nuts and Drive-In Trailer Hub Studs
    For 9/16" lug nuts we have the Trailer Wheel Lug Nut - 9/16" # 6-53. Then, for drive-in 9/16" wheel studs, which are 2-1/2" long, the correct part is the Trailer Hub Wheel Stud # 7-257. These are sold individually so you'll want to make sure you order the appropriate amount for your hub and wheels.

  • Wheel Stud Recommendation to Fit Dexter 7,000 lb Hubs
    Dexter 7,000 lb axle hubs come with either 1/2 inch wheel studs like the part # RG03-080 that you referenced or 9/16 inch diameter studs like the # 7-257. You'd need to measure what you have to know for certain.

  • Replacement 9/16 Inch Wheel Stud for a 7K AxleTek 8-Bolt Hub and Drum Assembly
    The wheel stud you need sounds very close to # K916WB25. I have included a picture showing the dimensions. Another option that is very close is # 7-257. It has a chart with its dimensions below the features section on its page. The other 9/16 options we have are either a thread in one, which is not likely what you have, and a shorter model that would not work for you.

  • Replacement Wheel Studs for Dexter P-12 D90 Axle
    Thanks for the photo. It gives me the further information needed to assist. The P-12 only gives the factory location from Dexter. The D-90 model is a huge help as it designates is a 9k axle. The correct hubs you would need for your Dexter D-90 axle is the part # 8-430-5UC3. Then the wheel stud replacements are # 7-223 for a 2 inch length or # 7-257 for a 2-1/2 inch length.
