The Multiquip 18190 is a genuine OEM Screw Hub Stud 1/2"-20 x 2-3/4" designed for Whiteman hydraulic power buggies in the WBH-16 and WBH-21 series, including models WBH-16EAWDF, WBH-16EAWD, WBH-21EF, WBH-16F, WBH-16EF, WBH-16E. As a genuine OEM component, part 18190 is manufactured to the same specification as the original hardware installed at the factory, ensuring a direct, secure fit in the wheel hub assembly. Sourced through DHS Equipment, this stud screw is the correct replacement when servicing or rebuilding the hub on your Whiteman buggy.
Key Features
- Genuine OEM Thread Specification — 1/2"-20 fine-thread pitch and 2-3/4" length match the original hub stud specification exactly, maintaining correct torque retention and clamping force at the wheel.
- Direct Hub Replacement — Engineered to install in the same position and orientation as the original stud, requiring no modifications to the hub bore or wheel hardware.
- Broad WBH Series Coverage — Confirmed fitment across WBH-16 and WBH-21 series Whiteman hydraulic power buggies, including AWD, electric start, foam-fill, and propane-capable variants.
- Structural Integrity at the Wheel — A worn, stripped, or broken hub stud compromises wheel retention and creates unsafe load-carrying conditions; replacing with the correct OEM stud restores the rated load capacity of the buggy.
- Safety-Critical Fastener — Hub studs are a load-bearing, safety-relevant component on powered material-handling equipment; using the correct OEM grade and thread form is essential for safe operation under full rated capacity.
A hub stud screw is the threaded fastener that anchors the wheel to the hub assembly on a power buggy. It carries the combined static and dynamic loads placed on the wheel during operation — including the weight of the machine, the operator, and a full load of concrete or material. When a hub stud is damaged, stripped, or sheared, the wheel cannot be properly torqued and secured, which creates a serious risk of wheel separation during use. Replacing a compromised stud promptly with the correct OEM part restores the full structural integrity of the wheel attachment.
