The Multiquip 03799400 Grub Screw is a genuine OEM Grub Screw designed for MQ41TDH trash pumps, MDR-9D power trowels, and MVH502DSB and MVH502DSB2 reversible plate compactors. As an authentic Multiquip OEM component, it is manufactured to the exact specifications of the original part — ensuring a correct, consistent fit every time. Verify your model code against the fitment list before ordering to confirm compatibility with your specific machine. DHS Equipment stocks this part as a genuine Multiquip replacement, so you can get your equipment back to work without guesswork.
Key Features
- Genuine OEM Specification — Manufactured to the same dimensional and material standards as the original Multiquip 03799400, delivering the exact thread engagement and holding force the application demands.
- Direct Drop-In Installation — Matches the original thread pitch and drive profile, so it seats and tightens using the same tooling and torque procedure as the factory part.
- Broad Cross-Equipment Fitment — Confirmed for the MQ41TDH trash pump, MDR-9D power trowel, and MVH502DSB and MVH502DSB2 reversible plate compactors — one part number spanning multiple machine families.
- Secure Locking Performance — A properly seated grub screw prevents rotational or axial movement between mating components; a loose or missing one allows unwanted play that accelerates wear on surrounding parts.
- Sourced Through an Authorized Multiquip Dealer — DHS Equipment supplies genuine Multiquip OEM parts, so authenticity and traceability are assured from the point of purchase.
A grub screw — also known as a set screw — is a headless fastener threaded along its full length and tightened directly into a component to lock a shaft, collar, or fitting in place without protruding beyond the surface. It works by applying clamping force between two mating parts, preventing rotation or linear movement under load. When a grub screw loosens, strips, or goes missing, the components it secures can shift unexpectedly, causing accelerated wear, misalignment, or mechanical failure in the assembly it anchors.
