Wacker Neuson 5000028756 Lock Nut #10-32 Hex Nylon Insert

The Wacker Neuson Lock Nut #10-32 Hex Nylon Insert is a genuine OEM fastener designed for the RD7, RD12, RD16, and RD880V tandem roller series, as well as WB16 Power Buggy models. Sourced directly from Wacker Neuson, this fastener meets the exact specifications used in original production, ensuring a secure and consistent installation. The fits an extensive range of walk-behind rollers and power buggies across multiple machine generations, making it a versatile stocking item for service teams and equipment owners alike.

Key Features

• Genuine OEM Fastener Integrity — The nylon insert provides a proven locking mechanism that resists vibration-induced loosening, critical on compaction equipment subject to continuous dynamic loads.
• Standard #10-32 Thread Form — Threads into existing hardware locations with no chasing or re-tapping required, maintaining correct clamp load across the joint.
• Broad Tandem Roller Fitment — Compatible with RD7, RD12, and RD16 series walk-behind tandem rollers, including foldable ROPS and standard ROPS configurations across multiple production runs.
• WB16 Power Buggy Compatibility — Also fits WB16A, WB16AE, WB16AF, WB16AS, and related WB16 variants, consolidating a single part number across your roller and buggy fleet.
• Vibration Resistance by Design — The nylon insert collar deforms slightly around the bolt thread on installation, creating a prevailing-torque lock that holds under the high-frequency vibration generated during compaction cycles.

A lock nut with a nylon insert — sometimes called a nyloc nut — uses a ring of nylon bonded inside the top of the hex nut body. When the mating bolt is driven through, the nylon deforms around the thread and creates a friction-based prevailing torque that prevents the nut from backing off under vibration or shock loads. On tandem rollers and power buggies, where structural and mechanical fasteners are subjected to constant vibration during operation, a compromised or missing lock nut can allow joints to work loose, leading to misalignment, accelerated wear on surrounding components, or structural failure. Replacing worn or single-use nylon insert nuts with the correct OEM specification part maintains joint integrity and keeps critical assemblies torqued to design values.
