The Multiquip 3291 is a genuine OEM U-Style Nut M6-1 x 0.8 4MM BK designed for a range of Multiquip ride-on trowels and mixers, including STXDF and PRX series power trowels and EM120S, EM120P, WM120SH, and WM120PH series mixers. As a direct OEM replacement, it is manufactured to the same specifications as the original hardware installed at the factory. Confirm your model code before ordering to ensure proper fitment across these equipment families.
Key Features
- Genuine OEM Hardware Grade — Manufactured to exact M6-1 x 0.8 thread specification, ensuring consistent clamping force and secure fastening on original mounting points.
- U-Style Retaining Design — The U-style profile allows the nut to slide onto a panel edge or bracket flange without requiring full nut access from behind, simplifying installation in tight assemblies.
- Broad Multiquip Fitment — Compatible with STXDF and PRX ride-on trowel series as well as EM120S, EM120P, WM120SH, and WM120PH mixer models.
- Corrosion-Resistant Black Finish — The BK (black) finish provides a protective coating that resists surface oxidation in demanding outdoor and concrete-finishing environments.
- Exact-Match Replacement — Using part number 3291 ensures the fastener matches the original thread pitch, size, and profile — critical for maintaining proper torque values and structural integrity at fastening points.
A U-style nut, sometimes called a U-clip nut or speed nut, is a spring-steel fastener that clips onto a panel edge, bracket, or slot, allowing a mating bolt or screw to thread into it without requiring a wrench on the nut itself. This makes it especially useful in assemblies where one side of the fastening point is inaccessible. When a U-style nut becomes deformed, stripped, or corroded, it can no longer hold proper thread engagement, which leads to loose panels, vibrating covers, or hardware that backs out under the sustained vibration of trowel or mixer operation. Replacing a worn U-style nut with the correct OEM part restores full clamping strength and prevents progressive loosening of the surrounding assembly.
