Wacker Neuson 5100015522 Washer, Lock, Split, Medium, 5/16

The Wacker Neuson Washer, Lock, Split, Medium, 5/16 is a genuine OEM component designed for the Vaccum Ready Sweeper series, including the 60", 72", and 84" heavy-duty pick-up broom configurations. Sourced directly from Wacker Neuson, this lock washer is manufactured to the same specification as the original hardware installed at the factory. Keeping the correct fastener hardware in place matters more than it might seem — the right washer ensures fastener integrity across the broom assembly and maintains secure, vibration-resistant connections throughout service life.

Key Features

• Genuine OEM Hardware Specification — Manufactured to the exact material grade and split profile of the original 5/16 lock washer, ensuring consistent clamping force and resistance to loosening under operational vibration.
• Drop-In Replacement — Matches the original 5/16 split lock washer profile exactly, seating into existing fastener positions on the broom assembly without modification.
• Broad Sweeper Series Coverage — Compatible with the 60", 72", and 84" Vaccum Ready Sweeper heavy-duty pick-up broom attachments, covering the full range of VRS broom widths.
• Vibration-Resistant Locking Action — The split design bites into mating surfaces under torque load, preventing fastener back-out during the continuous vibration and impact typical of heavy-duty sweeper operation.
• Correct Part, First Time — Ordering by Wacker Neuson part number 5100015522 eliminates guesswork on sizing and ensures you receive the hardware specified for your machine.

A split lock washer is a small but critical piece of fastener hardware. Placed between a bolt or nut and the mating surface, its split ends dig into both surfaces as the fastener is tightened, creating resistance that prevents the fastener from backing out due to vibration or repeated mechanical loading. On sweeper equipment — where broom assemblies are subject to constant vibration, impact, and rotational forces — a worn, flattened, or missing lock washer can allow fasteners to loosen over time, leading to component misalignment or detachment. Replacing worn or damaged washers with the correct OEM-spec part keeps fastened connections secure and the broom assembly operating as intended.
