The Multiquip 04115 is a genuine OEM Grub Screw designed for QP3TZ, QP2TZ, and LS300 series equipment. As a direct factory replacement, this screw meets the original engineering specifications, ensuring a flush, secure installation without the guesswork of sourcing a generic substitute. Sourced directly through authorized Multiquip supply channels, the 04115 is the correct part for maintaining the mechanical integrity of your machine. Confirm your model code before ordering to ensure compatibility with your specific unit.
Key Features
- Factory-Grade Thread Specification — Manufactured to the exact thread pitch and hardness grade of the original, ensuring full engagement and secure holding force without stripping or backing out under vibration.
- Drop-In Installation — Installs directly into the existing tapped bore with no modification to surrounding components — thread form and drive style match the OEM application.
- Confirmed Fitment — Compatible with QP3TZ and QP2TZ trash pumps and LS300 concrete pump models, covering both pump families in the Multiquip lineup.
- Maintains Clamping and Locking Function — A correctly installed grub screw prevents relative movement between mated components; a worn or missing screw can lead to shaft slippage, misalignment, and accelerated wear on surrounding parts.
- Genuine OEM Quality — Supplied as an authentic Multiquip OEM part, holding the same material grade and surface treatment as the original, so service life matches the manufacturer's design intent.
A grub screw — also called a set screw — is a headless fastener threaded through a collar, hub, or housing to bear directly against a shaft or mating surface, locking two components together without any protruding head. In pump and hydraulic drive applications like the QP3TZ, QP2TZ, and LS300, these screws are commonly used to secure impeller hubs, drive couplings, and pulley assemblies to their respective shafts. When a grub screw loosens or fails, the secured component can rotate or shift independently, causing vibration, noise, and potentially serious mechanical damage to the shaft or housing. Replacing a worn or missing grub screw promptly with the correct OEM part restores the clamping force needed to keep critical rotating assemblies properly positioned and running true.
