The Multiquip 50405301 is a genuine OEM Grub Screw M 6 X 45 designed for use across multiple Multiquip equipment families, including MVH502DSB2, MVH502DSB, MQ41TDH, and MDR-9D models. As a direct OEM replacement, this fastener is manufactured to exact dimensional tolerances to ensure correct seating and holding force in the application. Sourced from Multiquip and sold by DHS Equipment, the part delivers the same specification as the original hardware that left the factory. Confirm your model code against the fitment list before ordering to ensure this is the correct grub screw for your machine.
Key Features
- Exact Thread and Length Specification — M6 x 45mm dimensioning matches the OEM requirement precisely, ensuring correct engagement depth and clamping performance without modification.
- Genuine OEM Hardware Grade — manufactured to Multiquip's original material and hardness specification, delivering the holding strength this fastener type demands in a vibration-prone environment.
- Broad Cross-Family Fitment — verified for MVH502DSB2, MVH502DSB, MQ41TDH, and MDR-9D, covering reversible plate compactors, trash pump, and ride-on trowel applications.
- Secure Component Retention — a correctly torqued grub screw prevents shaft slippage and positional drift of the secured component; a loose or worn screw can cause progressive damage to mating surfaces.
- Direct-Install Replacement — threaded into existing bosses or collars with standard hex key tooling, making field or workshop replacement straightforward.
A grub screw — also known as a set screw — is a headless fastener threaded entirely along its length, used to lock a component such as a collar, pulley, or gear firmly onto a shaft or within a housing. It works by bearing its tip directly against the mating surface under torque load, preventing rotational or axial movement. When a grub screw loosens or strips, the secured component can shift under load, causing wear to both the shaft and the assembly it holds, and potentially leading to loss of drive or mechanical failure of the affected sub-assembly.
