The Multiquip 50128 Stud is a genuine OEM fastener component designed for RAMMAX walk-behind rollers and Hatz-powered trash pumps, including the RW1404, RW1404MR, RW1504HF, QP2TZ, and QP3TZ. As a direct Multiquip OEM part, the 50128 is manufactured to the exact material and dimensional specifications of the original, ensuring correct installation without fitment issues. This stud is sourced directly through the Multiquip OEM parts network and sold by DHS Equipment, giving you confidence in part authenticity and compatibility across the listed equipment families.
Key Features
- Genuine OEM Material Grade — Manufactured to Multiquip's original thread pitch, length, and tensile specifications — not a generic fastener substitute.
- Exact-Match Installation — Threaded to match the original mounting points on covered roller and pump models, seating flush without reworking the mating surface.
- Broad Fitment Coverage — Confirmed for RW1404, RW1404MR, RW1504HF (up to S/N 1534188), QP2TZ, and QP3TZ equipment.
- Structural Integrity Maintained — A correctly torqued stud holds critical assemblies in alignment; a worn or stripped stud can allow component shift, vibration loosening, or assembly failure under load.
- Cross-Family OEM Part — A single Multiquip OEM part number covering both roller and trash pump applications, simplifying parts ordering across your fleet.
A stud is a headless threaded fastener used to create a fixed anchor point in a housing or structural component, allowing a mating part to be drawn down and secured with a nut. Unlike a bolt, the stud remains threaded into the base material permanently, providing a consistent, repeatable clamping reference that is critical on high-vibration equipment such as compaction rollers and engine-driven pumps. When a stud becomes corroded, stretched, or cross-threaded, it compromises the clamping load of the entire fastener group — which can lead to cover leaks, misaligned components, or mechanical loosening during operation.
