The Multiquip 29342 Pop Rivet Backup Washer 3/16 Dia SS is a genuine OEM component designed for Whiteman ride-on power trowel models JWN24HTCSL and HHNG5. As a factory-sourced part, 29342 delivers the exact material grade and dimensional tolerancing required for a secure, lasting rivet connection on these machines. Stainless steel construction ensures the washer holds up to the moisture and mechanical stress common in concrete finishing environments. Verify your model code against the fitment list to confirm compatibility before ordering.
Key Features
- Stainless Steel Material Grade — Corrosion-resistant SS construction stands up to the wet, abrasive conditions of concrete finishing work without degrading over time.
- Exact 3/16" Diameter Specification — Machined to the correct 3/16" diameter so it seats flush against the rivet head and distributes clamping load evenly across the joint surface.
- Genuine OEM Sourcing — Manufactured to Multiquip's original design, ensuring the washer matches the fastener geometry used in the original assembly of these trowels.
- Direct Fitment for JWN24HTCSL and HHNG5 — Confirmed for Whiteman non-overlapping blade and heavy-duty ride-on power trowel models, so there is no guesswork on part compatibility.
- Maintains Structural Fastener Integrity — A properly sized backup washer prevents rivet pull-through and panel deformation; a missing or undersized washer can cause fastener failure and panel loosening under vibration.
A pop rivet backup washer is a small but critical fastener component that sits behind a pop rivet to spread the clamping load over a wider surface area. Without it, the rivet head can pull through thinner panels or sheet metal under vibration and load, leading to loose assemblies and potential structural failure in the affected joint. On ride-on power trowels like the JWN24HTCSL and HHNG5, where the machine operates under constant rotational vibration, correctly installed backup washers are essential to keeping panels, guards, and housings securely fastened.
