The Multiquip 363203 Wheel Lug Nuts 1/2 UNF 60 Con is a genuine OEM fastener set designed for Multiquip hydraulic-driven concrete pump models including the LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a direct OEM replacement, the 363203 is manufactured to Multiquip's original specifications, ensuring a correct thread engagement and seating angle on your pump's wheel hubs. Sourced through DHS Equipment as an authorized Multiquip parts distributor, you can order with confidence knowing you're receiving the correct part for your machine.
Key Features
- OEM-Correct Thread Specification — 1/2 UNF threading matches the original fastener spec, delivering full thread engagement with no risk of cross-threading or underloading at the wheel hub.
- 60-Degree Conical Seat — The 60 Con seating angle is matched to the wheel mounting surface on LS-series concrete pumps, ensuring proper load distribution and secure wheel retention when torqued to spec.
- Broad LS-Series Compatibility — Fits LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD hydraulic-driven concrete pumps, covering a wide range of Multiquip's Mayco pump lineup.
- Maintains Wheel Integrity Under Load — Correctly spec'd lug nuts keep wheels firmly seated during transport and on-site repositioning of the pump, preventing dangerous wheel movement or separation.
- Genuine OEM Part — Manufactured to Multiquip's original design, the 363203 replaces worn, stripped, or missing lug nuts with hardware that meets the same standards as the parts that came on the machine.
Wheel lug nuts are the threaded fasteners that secure the wheels to the hub of a machine. On towable equipment like the LS-series concrete pumps, properly torqued lug nuts are essential for safe transport — loose or incorrect fasteners allow wheel movement that can lead to vibration, stud damage, or wheel separation while the unit is being moved between jobsites. The 60-degree conical seat design on the 363203 is engineered to self-center as the nut is tightened, creating a secure, consistent clamp load. Replacing damaged or missing lug nuts with the correct OEM specification hardware restores safe towing capability and protects the wheel studs from the accelerated wear that undersized or mismatched fasteners cause.
