Specs:
This trailer hub has a zinc coating that resists corrosion, making it ideal for use on your boat or snowmobile trailer. All GAL-DEX hubs undergo a test in which they are sprayed with a 5-percent salt solution to determine corrosion resistance over time. These products are able to withstand 500 hours of constant exposure to the saltwater mist. This 500-hour salt spray rating indicates that a product is not only durable enough to last in freshwater environments, but it can also be used on trailers that come into contact with saltwater.
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.
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.)
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 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.

Today we're going to review part number 8-231-50. This is the Dexter Trailer Hub for 5,200 lb to 7,000 lb axles. As you can see it is an 8 on 6 1/2" bolt pattern and has the GAL-DEX finish on it. Basically this is a galvanized marine-grade trailer hub which will fit on Idler axles. It does include the inner and outer bearing races which are press-fit in there already, but it does not include any of the bearings, the grease seal, the grease cap, or the lug nuts. Those are all sold separately.
We do sell them on our website and if you go to the product page for this hub, it will list all those part numbers you would need. This trailer hub has GAL-DEX zinc coating that will resist corrosion. Makes it ideal for use on your boat or snowmobile trailer, and it's durable enough for saltwater applications. All of the GAL-DEX hubs are able to withstand 500 hours of constant exposure to the saltwater mist. This 500 hour salt spray rating will indicate that this product is not only durable enough to use in freshwater environments, but it also could be used on trailers in a saltwater environment. Now again, the application on this hub is 5,200 lb axles, 6,000 lb axles, and 7,000 lb axles.
The bolt pattern is 8 on 6 1/2". The wheel stud's diameter is 1/2". Weight capacity on one of these hubs is 3,500 lb, so one matched with one on the other side on the axle will get you your maximum of 7,000 lb. Again, the bearings, the grease seal, the grease cap, and the lug nuts are all sold separately. That should do it for the review on part number 8-231-50, the Dexter Trailer Hub for 5,200 lb to 7,000 lb axles with the 8 on 6 1/2" bolt pattern.
