The Multiquip EM504456 Cap Screw is a genuine OEM fastener designed for Multiquip concrete pumps and power buggies, including the LS300GK, LS300, LS400, LS500, LS600, WTB-16, and WTB-16PD. As a factory-sourced component, EM504456 is manufactured to the exact thread pitch, grade, and dimensions specified for these machines, ensuring a true drop-in fit across compatible models. Sourcing the correct OEM cap screw matters — an improperly sized or off-grade fastener can compromise the integrity of critical assemblies on heavy-use equipment. DHS Equipment stocks this part ready to ship so you can keep your machine secured and back on the job without delay.
Key Features
- Correct Thread Grade and Dimensions — Manufactured to the exact torque rating, thread pitch, and head specification called out in the Multiquip parts manual, so the joint clamps to the right load.
- Genuine OEM Sourcing — Supplied directly through the Multiquip OEM parts network, meaning this is the same fastener installed at the factory — not a generic hardware-store substitute.
- Broad Model Compatibility — Verified fitment across LS300GK, LS300, LS300G, LS400, LS500, LS600 concrete pump models and WTB-16 and WTB-16PD power buggies.
- Structural Integrity Where It Counts — A correctly rated cap screw maintains proper clamping force on high-vibration assemblies, preventing loosening, misalignment, and premature wear of surrounding components.
- Direct OEM Part Number Cross-Reference — Order by part number EM504456 with confidence — this is the authoritative Multiquip reference for this fastener across all listed models.
A cap screw is a precision-threaded fastener used to join and clamp structural or mechanical components together within a machine assembly. Unlike a standard bolt, a cap screw is designed to thread directly into a tapped hole, applying controlled clamping force without a nut. On equipment like concrete pumps and power buggies — which operate under sustained vibration and mechanical load — using a fastener of the correct grade and thread specification is critical. A worn, stripped, or incorrect cap screw can allow components to shift or separate, leading to accelerated wear on mating parts and potential failure of the assembly it secures.
