Video Transcript for Review of Redline Trailer Hub Drive-In Wheel Stud 9/16 Inch X 2 Inch - 7-223

Hi, everybody. Andy here with And today, we're gonna take a brief look at this trailer hub drive-in wheel stud. This is going to replace one trailer hub drive-in's wheel stud and this is 9/16 of an inch in diameter. And retrieving my ruler here, you can see that it is two inches long. And to further help you determine if this is going to work for you, on your screen, I am including a diagram with some additional measurements.

So again, you see the thread diameter is listed at 9/16 of an inch. The stud length is two inches. And then some further dimensions, the spline length is listed along with the base length and the spline diameter. So hopefully, that will help you determine if this will work for your particular application. We also have this diagram with those measurements listed on this product page.

So, feel free to visit the product page to get those measurements and that diagram. So, you are going to get one replacement stud. And that's going to conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy.

Thank you for joining me..

Replaces 1 trailer hub drive-in wheel stud. 9/16" Diameter x 2" long.


The folks a trailer are the very best. Professional, friendly, and very knowledgeable. This product was just purchased to carry as a spare part for my fifth wheel trailer. Anything I have ordered from etrailer has always been of the best quality. Love their customer service.


worked perfectly


Parts arrived on time via UPS. Took them right over to the machinist and within an hour was able to pick up my hub & drum. The machinist works at an auto parts store and the distributors for the store couldn't match the specs of the Dexter Wheel Lugs so had to special order these from etrailer. Got excellent service. Suggest you follow the instructions from Dexter for reassembly of the wheel and axle system.
I recommend you also order the end of spindle snap ring as well as the magnet clips for this job.


I talked to Rebecca to verify sizes on the parts I ordered. She took time to confirm the sizes and tracked the order so it would go out the same day I ordered. Excellent customer service and much appreciated. Big thumbs up!



We continue to purchase products from etrailer - still outstanding service.


product did not fit. You did not have the size i needed.

For the nine sixteenth wheel stud we offer two sizes. One is 2 inches long and the other is 2.5 inches long. You will wanted to measure the wheel studs that you have.


couldn't find anywhere but here and etrailer it so easy to find they correct one in minutes


Fast, quick delivery and very easy to order on line. Studs fit great and are exactly what I needed to get my trailer up and running again. I’d buy from them again as well as recommended others to buy from them.

  • 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.

  • Replacement Wheel Stud for a 2013 Ice Castle Trailer
    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...
