The Multiquip 04144401 Grub Screw is a genuine OEM component designed for MVH406, MVH-406DSZ, and QP4TZ series equipment. As an authentic Multiquip OEM part, it is manufactured to the same specifications as the original hardware installed at the factory, ensuring a direct, hassle-free replacement. Confirmed fitment spans the MVH406 and MVH-406DSZ reversible plate compactors as well as the QP4TZ trash pump, making it a versatile hardware item across two Multiquip equipment families. Keep a spare on hand to avoid unnecessary downtime during routine service or field repairs.
Key Features
- Genuine OEM Hardware Grade — Manufactured to exact thread pitch, hardness, and dimensional tolerances specified for Multiquip equipment, so the screw seats and holds as intended.
- Drop-In Replacement — Matches the original installation point precisely, threading directly into the existing bore without any modification to the host assembly.
- Broad Fitment Coverage — Compatible with MVH406 and MVH-406DSZ reversible plate compactors and the QP4TZ trash pump, covering two distinct Multiquip equipment families with a single part.
- Secure Component Retention — A properly torqued grub screw locks rotating or sliding components firmly in position, preventing unwanted movement that can accelerate wear on surrounding parts.
- Part Number 04144401 — Cross-reference against your service manual or parts diagram using this OEM number to confirm the correct screw before ordering.
A grub screw — also known as a set screw — is a headless fastener threaded along its full length and tightened flush with or below the surface of the host component. Its primary role is to lock a shaft, collar, pulley, or fitting in place by applying direct clamping force against the mating surface. When a grub screw loosens or strips, the component it secures can shift or rotate out of position, leading to vibration, misalignment, accelerated wear, or loss of function in the assembly. Replacing a worn or damaged grub screw promptly with the correct OEM specification part restores the intended holding force and keeps the surrounding components operating as designed.
