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.


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.)


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.)


Bolt Pattern - Side

Measuring the distance (D) 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"

Video Transcript for Dexter Axle Trailer Hubs and Drums - Hub with Integrated Drum - 8-285-9UC3 Review

Speaker 1: Today we're going to take a look at the Dexter Oil Bath Trailer Hub and Drum Assembly with the 8 on 6-1/2" bolt pattern. Now the application for this hub and drum assembly is 8000-lb Dexter Axles. By spinning this around I'll show you inside, you can see that it will work with both electric and hydraulic brakes. The drum dimension on this is going to be the inside diameter is 12-1/4". The width on it is right at 3-3/8" wide. Again the bolt pattern on this is an 8 on 6-1/2" bolt pattern.

Now this part will include everything shown here on the table. Will include the bearings, the oil seal, the oil cap, and the lug nuts.And just to go through each one and the part numbers. The inner bearing it uses, it comes with is 25580. Outer bearing is 02475. Comes with the unitized oil seal because it's an oil bath set up, it's part number 10-63.

Comes with the oil cap, which is a clear poly carbonic cap, which includes both the O ring and the rubber plug, part number on this cap is KPCAP. And it comes with 8 of the 9/16s by 18 lug nuts, part number 6-53. And the weight capacity on this is 4,000 lbs per assembly, so when you use just one, on the other side it will meet the 8,000 lb weight capacity of the Dexter Axle. But that should do it for the review on the Dexter Oil Bath Trailer Hub and Drum Assembly with the 8 on 6-1/2" bolt pattern.

  • How to Tell if Trailer Hub 8-258 Will Fit Spindle
  • We do have the Dexter trailer hub and drum part # 8-285-9UC3 which might work but you would need to verify a few things. This is an 8k oil-bath hub with a bolt pattern of 8 on 6-1/2 inches.
