Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Measuring Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Measuring Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Measuring Bolt Pattern - Side-to-Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Average Customer Rating:  4.7 out of 5 stars   (7 Customer Reviews)

10" Hub-and-drum assembly features 5 on 4-1/2 bolt pattern. Includes wheel bolts and races. Bearings, seal and grease cap sold separately.


This was the third order I placed with eTrailer in quick succession as I rebuilt the surge-brake system on my boat trailer. Your videos were very helpful and your customer service was awesome. The price on everything I purchased was very good. All my orders arrived on-time and fit perfectly. Thank you! I'll purchase from you again.


As always, etrailer is exact, on time, packaged well and good quality with competitive pricing - way to go et.


Only issue I had was this hub needed a different sized seal than the hub I had. Originally bought a replacement for my seal, then noticed I needed a larger one that would still fit my axle. Worked with local parts store and we found one that would fit after measuring. Everything else was fine.


1st Thing!! Great / Excellent Service!!!!!
product is exactly as stated. Looks like it's made of quality materials.
Fit is great.
If it were not for the help from there ordering Tec / Christina; I would have known to order this fit right the first time item.
Thanks etrailer


the products that I ordered were exactly what I needed. fast shipping. I will order from them again if I need something


good product at good price.

Sold the trailer so it worked out good.

  • 5 on 4-1/2 Hub and Drum for Hydraulic Brakes on a Trailer with L68149 and L44649 Bearings
    Hub and drum # T1543900CB042 uses the same inner and outer bearings as what you have now and it has the proper bolt pattern. It does not come with the bearings or seals but races are already installed. For a bearing kit use # BK2-100. I have included a link to a video on the hub and drum assembly for you.

  • Availability of Hub and Drum Assembly to Fit 2,200-Lb Torsion Axle With 10-Inch Wheels
    The Titan 5 on 4-1/2 Hub and Drum Assembly, part # T1543900CB042, you have referenced is a 10-inch hub and drum assembly. A 10-inch size wheel will not fit this assembly. This hub and drum assembly will use 13, 14, or 15 inch wheels. The hub and drum assembly that would fit a 2,200-lb axle that uses 10-inch wheels would be the Titan 5 on 4-1/2 Hub and Drum Assembly, part # T1540500CB042. This is a 8-1/2 inch hub and drum assembly and will accept 10-inch wheels.You will also need to order...

  • eTrailer Axle Technology Trailer Hub and Drum Assembly compared to Titan Hub and Drum
    In comparing the eTrailer Axle Technology Trailer Hub and Drum Assembly, # AKHD-545-35-EZ-K, with the Titan Hub and Drum, # T1543900CB042, there are very few differences. The differences are mostly in the casting of the part, not in the function or fit of it. Both assemblies will work on the same 3500 lb axle and # 84 spindle. They are both designed to use the same inner and outer bearings and fit a 10 inch assembly. Either one will work just fine for your application. As far as a hole...

  • Are Drums Included with Demco Hydraulic Brake Kit for 3.5K Axles # DMSB18794M-93M
    No, the brake drums are sold separately from Demco Hydraulic Brake Kit # DMSB18794M-93M. The reason is that not everyone needs to replace both the brake assemblies and the drums. There are also at least 5 different bolt patterns for the hub and drum assemblies for 3500 pound axles. The most common bolt pattern is 5 on 4-1/2 so in that pattern for hydraulic brake drums you could use # T1543900CB042 which is sold in quantities of 1.

  • Recommended Replacement 3,500 Lb Axles With Electric Brakes For 2003 Sno Pro Trailer
    We do offer 3,500 lb axles that may work for your Sno Pro trailer. The axles we offer are not torsion axles but may serve your purpose well. I recommend the Trailer Axle w/ Electric Brakes, part # e43SR. These 3,500 lb axles have the electric brake and hubs installed and also feature the EZ-Lube spindle which makes lubrication easy. The axles have a hub-face-to-hub-face measurement of 89 inches and spring-center-to-spring-center length of 74 inches. I have attached a product review video...
