Multiquip 0448 Flat Washer SAE 7/16

The Multiquip 0448 is a genuine OEM Flat Washer SAE 7/16 designed for a wide range of Multiquip ride-on power trowels and flat saws. As a direct factory replacement, this washer is sourced to Multiquip's original hardware specifications and confirms compatibility across models including STX55, HTX44, HHN34, SP118, and SP2S20H. Whether you are servicing a Whiteman ride-on trowel or maintaining a Street Pro flat saw, the 0448 installs as a direct drop-in at the correct seating diameter. Having the right hardware on hand keeps assembly torque distributed properly and ensures fastened connections hold to spec across demanding field applications.

Key Features

• Genuine OEM Hardware Spec — Sourced directly from Multiquip, this washer meets the original SAE 7/16 dimensional standard used at the factory, so load distribution and clamping force remain consistent with the original assembly.
• Broad Cross-Equipment Fitment — Compatible with STX55, HTX44, HHN34, HHN31, JTNS/JTNSW series ride-on trowels, SP118, and SP2S20H flat saws — a versatile hardware item to stock for mixed fleets.
• Correct Bearing Surface for Fastener Integrity — The SAE 7/16 flat washer format provides the proper bearing surface area to prevent bolt heads and nuts from pulling through or deforming adjacent materials during torquing.
• Exact Replacement Part Number — Part number 0448 matches Multiquip's own service documentation, eliminating guesswork when cross-referencing your parts list or service manual.
• Supports Reliable Assembly Across High-Vibration Equipment — Trowels and pavement saws operate under sustained vibration; correctly rated and properly seated washers help maintain fastener clamp load over time in these conditions.

A flat washer serves a straightforward but critical role in any bolted assembly — it distributes the clamping load of a fastener across a wider surface area, protecting the material beneath and helping the connection maintain its holding force under load and vibration. On ride-on power trowels and flat saws, where engines, blades, and rotating components generate constant vibration, properly seated hardware like the 0448 Flat Washer SAE 7/16 is essential to keeping fastened joints secure. A missing or incorrect washer can allow fasteners to loosen prematurely, leading to misaligned components or accelerated wear at the joint.
