The Multiquip 30057 is a genuine OEM Fastener Lead Washer SS Medium designed for EHHNK5 and HHNG5 ride-on power trowel models. As a direct Multiquip OEM part, the 30057 is manufactured to the same specification as the original component installed at the factory, ensuring a correct fit without guesswork. This washer is confirmed compatible with the EHHNK5 International Ride-On Power Trowel and the HHNG5 Whiteman Ride-On Power Trowel series. Sourcing the correct OEM hardware keeps your trowel running as intended and avoids the callbacks that come from using undersized or mismatched fastener components.
Key Features
- Genuine OEM Stainless Steel Grade — Sourced directly from Multiquip, this washer meets the original material specification for corrosion resistance and load-bearing performance in trowel applications.
- Correct Medium Southco Profile — The medium Southco sizing ensures proper seating and clamping force distribution, dropping directly into the original fastener position without alteration.
- Confirmed Fitment for EHHNK5 and HHNG5 — Verified for use on the EHHNK5 International and HHNG5 Whiteman ride-on power trowel models, so you can order with confidence.
- Hardware Integrity Under Continuous Vibration — Ride-on trowels generate sustained vibration during finishing operations; a correctly spec'd washer maintains fastener torque retention and prevents joint loosening over time.
- Direct OEM Replacement — Part number 30057 matches the original component exactly, eliminating the risk of misfit hardware that can lead to fastener backing out during operation.
A fastener lead washer serves as a load-distributing interface between a fastener head or nut and the mating surface it secures. On ride-on power trowels, where engine-driven blade assemblies create continuous vibration and torque loads, washers play a critical role in keeping fastened joints stable and preventing hardware from loosening or backing out during operation. A worn, undersized, or incorrect washer can allow the fastener to pull through or lose clamping force, which may lead to loosened components and uneven trowel blade performance.
