The Multiquip EM50448 Grub Screw M6X30 is a genuine OEM fastener designed for use across multiple Multiquip equipment families, including MVH308DZ and MVH508DZ reversible plate compactors, QP2TZ and QP3TZ trash pumps, RW1404MR rollers, and LS300P concrete pumps. As a direct OEM replacement, EM50448 is manufactured to the exact thread pitch, grade, and dimensional tolerances specified for these machines. Sourcing the correct grub screw ensures secure component retention and prevents costly slippage or misalignment during operation. DHS Equipment stocks this part to help you get your equipment back in service fast.
Key Features
- Exact Thread Specification: — M6x30 sizing matches the precise thread pitch and engagement depth required by the original design, ensuring full thread contact and secure clamping force.
- Genuine OEM Construction: — Manufactured to Multiquip's original material grade and hardness standards for a grub screw, so torque retention holds under vibration-heavy operating conditions.
- Broad Cross-Family Fitment: — Compatible with MVH308DZ, MVH508DZ, QP2TZ, QP3TZ, RW1404MR, and LS300P equipment, making it a versatile stocking item for mixed Multiquip fleets.
- Drop-In Installation: — Headless set-screw design installs flush into the existing threaded bore with a standard hex key — no machining, tapping, or additional hardware needed.
- Vibration Resistance: — A correctly installed grub screw of the proper grade maintains component position under continuous cyclic loading; an incorrect or worn screw can allow shaft or collar movement that accelerates wear on surrounding parts.
A grub screw — also known as a set screw — is a fully threaded, headless fastener used to lock a component such as a collar, gear, or shaft fitting firmly in position against a shaft or within a bore. Without it, rotating or sliding components can shift under load, causing misalignment, accelerated wear, or outright mechanical failure. Using the correct part number and grade is critical: an undersized or lower-grade screw may strip under torque or back out during vibration, while an oversized screw can damage the threaded bore and the component it is meant to secure.
