Today we're going to take a look at the Replacement Screw-In Trailer Hub Wheel Stud. This is a 1/2 inch diameter by 2 inches in length, and this is for a quantity of one. Now, this 1/2 inch stud is designed to replace a damaged wheel stud on your trailer hub. Does have a coarse threaded section of the stud right here. This will screw into the threaded hole on your trailer hub. Then the finer threaded section right here of the stud is what will go through the bolt 00:00:23 hole on your trailer wheel, and when used with a 1/2 by 20 size wheel lug nut will hold your tire and wheel to your axle.

I do happen to pull a 1/2 inch by 20 lug nut, a standard lug nut. You can see when this is installed into your hub, put your wheel up on the stud, and then just put your lug nut on there and torque it down to the correct specification. Now, these bolts are grade five bolts. A few measurements on this. The overall length, total end-to-end is 2 inches. Now the threaded length on both ends, the length of the threaded section on both ends is going to be right at 7/8 of an inch.

The differences on these, the thread size on the core section right here is a 1/2 inch by 13 threads per inch, and on the fine section, that's where the lug nut attaches to, will be the 1/2 inch by 20 thread per inch. That should do it for the review on the Replacement Screw-In Trailer Hub Wheel Stud, 1/2 inch diameter, 2 inches in length, and a quantity of one.

I've been trying to find studs to replace bad ones on an older utility trailer I have and the only place I could find them was at etrailer. I never realized just how many products they carry. Their web site is very easy to navigate, the ordering process was extremely simple, and the shipment arrived within just a couple of business days! Much better than most of the other websites I have used in the past. I will recommend this web site to all my friends looking for any trailer or towing part in the future. Thanks! 97472

  • Screw in Trailer Hub Wheel Stud 1/2 Inch to Replace Coarse Thread Lug Bolts

  • Using Redline # 25-51 Wheel Stud on Fayette Dayton Brake Drum
    The portion of the # 25-51 stud that would thread into the drum is 1/2 inch diameter x 5/8 of an inch in length. The threads are coarse, with a 13 threads per inch thread pitch. You should be able to compare this with one of your current lug bolts to see if there's a match. Redline couldn't tell me if the stud is a correct replacement for your Fayette Dayton brake drum.

  • Can Studs be Installed and Used Instead of Bolts for Trailer Hubs/Wheels
    You very well could use wheel studs instead of bolts by installing screw-in studs like the 1/2" x 2" Redline # 25-53 or # 25-51, or the 9/16" x 3" Redline # 25-11. Just be sure that the stud is the correct size, the middle opening on your new wheels is larger than the hub bore, and that your wheels accept coned lug nuts like part # CE11051. If all of that matches up then you are good to go!

  • How to Determine Wheel Stud Replacement for Boat Trailer Hub H-1377
    Based on my research it looks like you have a hub for a 3,500 lb axle, though we do not have any exact reference for an H-1377 hub to go off of. You only need to know whether your hub uses screw-in or drive-in studs as well as the length of stud you need. This is going to require you to remove one of your wheel studs and if they are drive-in they will have a head on them like the 1/2" x 2-1/2" Wheel Stud # 165995. A screw-in like the 1/2" x 2" Wheel Stud # 25-51 will be completely threaded. I...

  • Replacement 1/2 Inch Screw-In Wheel Studs
