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 - 8-393-4UC3 Review

Speaker 1: Today we're going to take a look at the Dexter trailer, hub and drum assembly for 7,200 pound axles that are manufactured after 1999. Has an eight on six and a half inch bolt pattern. Now this trailer and hub drum assembly will provide the surface area for your break show to grip when the break is activated. Now it is compatible with both electric and hydraulic drum breaks. It is a sturdy iron construction. It includes everything laid out here on the table: the hub and drum assembly, the larger bearing, which is the inner bearing, it's part number 25580, outer bearing, which is the smaller of the two, is 02475, now the bearing races that those sit in are already reinstalled in the hub.

It does use the double lip grease seal, the grease cap, and has eight of the 9/16ths lug nuts.Specs on this. The application for this hub and drum is 7,200 pound trailer axles, manufactured after 1999, and the reason they do that is after 1999 they went to four bolt brake flange. The axles before 1999 used the nine bolt break flange. So, this one is designed for the newer ones with the four bolt brake flange. Wheel size that will fit on this is 16 inch up to 17 1/2 inch diameter wheel.

The drum dimension, in other words the diameter from here to here on the inside, is 12 and 1/4 inches. The width is 2 1/2 inches wide. This is designed to work with the 12 and 1/4 inch break assemblies. Bolt pattern on this is a eight on a six and a half inch bolt pattern. The grease cap flange diameter, the grease cap that fits on the outside here is gonna be 2.66 inches, and the wheel lug side is 9/16x18.

Weight capacity on this hub and drum is 3,600 pounds, so when you match this with one on the other side of the axle, it'll meet your 7,200 pound axle capacity.That should do it for the review on the Dexter trailer hub and drum assembly for 7,200 pound axles manufactured after 1999, with the eight on six and a half inch bolt pattern.
