The Multiquip 504 is a genuine OEM Cap Screw engineered to fit a wide range of Multiquip, Whiteman, Essick, and Mayco equipment across multiple product families. As an OEM-verified fastener, part 504 meets the exact specifications required for correct clamping force, thread engagement, and torque retention across every compatible application. This Cap Screw is confirmed for use on concrete pumps, plate compactors, mixers, rollers, power buggies, trash pumps, walk-behind trowels, and more — including models LS300GK, EM120, EM120P Series, EM120S Series, EM12M Series, EM70P/S. Sourcing the correct OEM fastener ensures proper assembly integrity and prevents premature joint failure across all listed equipment.
Key Features
- Genuine OEM Thread and Grade Specification — Manufactured to the exact thread pitch, diameter, and material grade specified for each compatible application, ensuring correct torque values are achievable without risk of stripping or under-clamping.
- Direct-Replacement Fastener — Drops into existing bolt holes and mating threads without rework, maintaining original joint geometry across all listed equipment families.
- Exceptionally Wide Fitment Coverage — Compatible with concrete pumps (LS300GK, LS400, LS500, LS600), plate compactors (MVH308DE, MVH408DE, MVH508DE), Whiteman and Essick mixers (WM70S/P, WM90S/P, EM120, PRO12, PRO20), rollers (AR13H, RW1404, V304EH), power buggies (WBH-16, WTB-16), trash pumps (QP2TZ, QP3TZ, QP4TZ), and walk-behind trowels (J Series, B Series).
- Assembly Integrity Across High-Vibration Environments — Correct fastener spec is critical on compaction and concrete equipment where vibration loads can cause undertorqued or mismatched hardware to loosen in service, leading to component shift or structural separation.
- Backed by Multiquip OEM Parts Support — Supplied as a genuine Multiquip part, ensuring traceability and compatibility confidence when maintaining equipment across a mixed fleet.
A cap screw is a precision-threaded fastener used to clamp and secure components together, typically threading directly into a tapped hole rather than a nut. On construction equipment such as concrete pumps, compactors, and mixers, cap screws are used throughout the drivetrain, housing assemblies, guards, and mounting brackets where a controlled clamp load is essential. Using a fastener with the incorrect grade, thread pitch, or head size can result in inadequate clamping, fastener failure, or damage to threaded bores — all of which can compromise the structural integrity of critical assemblies and lead to unplanned repair downtime.
