Wacker Neuson 5000029117 Lock Nut M6, Hex, Serr, Flange

The Wacker Neuson is a genuine OEM Lock Nut M6, Hex, Serr, Flange designed for a broad range of Wacker Neuson equipment, including RD16 tandem rollers, RT82-SC2 and RT56-SC2 vibratory trench rollers, CRT ride-on concrete trowels, GP and G-series portable and skid-mounted generators, LTW and LTN light towers, and HI indirect-fired air heaters. As a genuine OEM component, it is manufactured to the same specification as the original hardware installed at the factory, ensuring correct fit without the need for sizing adjustments. This fastener is stocked as a direct replacement to support scheduled service and unplanned repairs across the extensive range of compatible Wacker Neuson machines.

Key Features

• Genuine OEM Specification Fastener — Manufactured to the exact thread class, hardness, and flange geometry specified by Wacker Neuson, so clamping load and torque values remain within design limits for each application.
• Serrated Flange Locking Design — The integrated serrated flange bites into the mating surface on installation, providing mechanical resistance to loosening from vibration — critical on compaction, trowel, and generator equipment subject to continuous dynamic loads.
• Direct Drop-In Replacement — M6 thread pitch and flange diameter match the original hardware exactly, allowing installation with standard hand tools without reworking mounting surfaces or hardware locations.
• Wide Cross-Equipment Compatibility — A single part number covers RD16 tandem rollers, RT and RTL/RTK/RTx trench roller families, CRT ride-on trowel series, GP and G-series generators, LTW and LTN light towers, HI air heaters, and WB power buggies, simplifying parts inventory management across mixed fleets.
• Vibration Resistance Where It Matters Most — On vibratory compaction and troweling equipment, standard hex nuts can back off over time under cyclical loading; the serrated flange on 5000029117 maintains joint integrity and prevents fastener-related hardware failures in the field.

A serrated flange lock nut combines a standard hex nut with an integrated washer-style flange and a ring of radial serrations on the bearing face. When torqued down, the serrations embed into the mating surface and create a mechanical interlock that resists rotational loosening caused by vibration and dynamic loads — both of which are present in compaction rollers, concrete trowels, generators, and light tower frames. Unlike a plain nut paired with a separate lock washer, the one-piece design keeps the joint clamped at the intended preload without adding components. When a lock nut loses its locking effectiveness — either through reuse after multiple removals or physical damage to the serrations — the fastened joint can loosen progressively, leading to misalignment, wear of mating components, or structural failure at the connection point.
