Dexter 90 Degree Cone Nut 008-430-90 for Clamp Ring Hub Assemblies, 9,000-15,000 lb Axles

The Dexter 90 Degree Cone Nut, part number 008-430-90, is the specified fastener for hub assemblies that use a clamp ring on Dexter medium duty trailer axles. It is designed to seat against the clamp ring to properly preload and retain the wheel bearings on one-piece hub assemblies. This cone nut is used on 9K, 10K, and #13G General Duty one-piece hubs within Dexter's medium duty axle line, which covers axle capacities from 9,000 to 15,000 pounds.

When a clamp ring is present on the hub assembly, the 90 degree cone nut is the required fastener; the flange nut is only used as an alternate when a clamp ring is not part of the assembly. Selecting the correct nut for the hub configuration is important for proper bearing preload and safe hub operation. This part is sold as the genuine Dexter cone nut for these applications.
