The Multiquip 50400300 is a genuine OEM Hex Screw M 8 X 40 designed for MVH502DSB, MVH502DSB2, MDR-9D, and MQ41TDH equipment. As a direct factory replacement, this fastener meets the exact thread pitch, shank diameter, and length specifications called for in the original build. Sourced directly through Multiquip's authorized parts network, 50400300 ensures you're installing the correct hardware the first time.

Key Features
- Genuine OEM Fastener Grade — Manufactured to the same thread class and tensile rating as the original hardware, ensuring the bolt engages and torques correctly in the threaded bore.
- M8 x 40 Hex Drive Configuration — Standard metric hex-head profile installs with common 13 mm tooling, dropping straight into existing fastener positions without chasing threads or adapting hardware.
- Broad Cross-Equipment Fitment — Confirmed for MVH502DSB and MVH502DSB2 reversible plate compactors, MDR-9D ride-on power trowel, and MQ41TDH trash pump applications.
- Structural Integrity Where It Counts — Correctly spec'd fasteners maintain clamping force on covers, guards, and housings; undersized or mismatched bolts can back out under vibration, leading to component loosening or damage.
- Direct OEM Part Number Reference — Part number this part matches Multiquip's own parts documentation, making cross-referencing against your service manual or parts diagram straightforward.
A hex screw is a threaded fastener with a hexagonal head, designed to be driven by a wrench or socket to clamp two or more components together with controlled torque. In vibration-intensive equipment such as plate compactors, power trowels, and trash pumps, fasteners are subjected to constant cyclical stress that can cause incorrect or worn hardware to loosen prematurely. Using the correctly specified M8 x 40 fastener ensures the joint maintains the clamping load the manufacturer engineered for, keeping covers, brackets, and assemblies securely seated through normal working loads.
