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 - 8-218-9 Review

Speaker 1: Today we're going to take a look at the Dexter Oil Bath Trailer Hub and Drum Assembly for 8,000 pound axles. Has an 8 on 6 and 1/2 inch bolt pattern. Now this trailer hub assembly will fit 8,000 pound Dexter oil bath axles. Works with both electric and hydraulic brakes. It is designed to fit the 12 and 1/4 inch diameter by 3 and 3/8 inch wide brake drums.Now the inner and outer bearings, the oil seal, the oil cap are all sold separately, and on this product page it will list the part numbers that are needed. The bearing races are pre-installed in the hub.

The outer race bearing race you can see right there, and if we turn around the inner bearing race is right in there. The lug nuts you can see are included.Again, the application is 8,000 pound Dexter oil bath trailer axles. The drum dimension after measuring it would be 12 and 1/4 inches by 4 inches wide. Bolt pattern again is 8 on 6 and 1/2 inches. The wheel stud diameters are 9/16.

The lug nuts that are included are 8 of the 9/16 by 18 thread per inch lug nuts. The hub pilot diameter on this one, it's going to be 4.56 inches, and the weight capacity is 4,000 pounds on this one, so when this is used with one on the other side it'll feature 8,000 pound capacity on the axle.But that should do it for the review on the Dexter Oil Bath Trailer Hub and Drum Assembly for 8,000 pound axles with the 8 on 6 and 1/2 inch bolt pattern.
