Multiquip EM934 Washer Bolt 6X20

The Multiquip EM934 Washer Bolt 6X20 is a genuine OEM fastener designed for use across multiple Multiquip equipment families, including the QP402H centrifugal pump, V30-W2-LD and V30-W2-R walk-behind rollers, RW1403HF roller, and MVH304GSB reversible plate compactor. As a direct OEM replacement, EM934 is manufactured to the exact dimensions and material grade specified for these machines, ensuring correct clamping force and secure assembly at every installation point. Sourced directly through authorized Multiquip distribution, this bolt is the right call when accuracy and fitment confidence matter most.

Key Features

• Genuine OEM Fastener Grade — Manufactured to Multiquip's specified tensile strength and thread tolerance for the 6x20 bolt profile, so clamping load stays consistent across service intervals.
• Integrated Washer Head Design — The captive washer distributes clamping force evenly across the mating surface, reducing the risk of surface damage or fastener loosening under vibration.
• Broad Cross-Family Fitment — A single part number covering QP402H centrifugal pumps, V30-W2-LD, V30-W2-R, and RW1403HF walk-behind rollers, and the MVH304GSB plate compactor makes EM934 a practical stock item for mixed Multiquip fleets.
• Vibration-Resistant Holding Power — Critical on compaction and roller equipment where constant mechanical vibration can work conventional fasteners loose; the washer bolt format maintains secure joint integrity through extended operation.
• Direct OEM Drop-In Replacement — Thread pitch, length, and head geometry match the original specification, so EM934 installs in place of the factory bolt without reworking surrounding hardware or mating components.

A washer bolt combines a hex bolt and an integrated washer into a single captive fastener, eliminating the need for a separate flat washer during assembly. On equipment subject to continuous vibration — such as plate compactors, walk-behind rollers, and pump units — maintaining correct fastener torque is essential to keeping housings, guards, and mechanical assemblies securely joined. When a washer bolt is worn, stripped, or missing, joint integrity is compromised, which can allow components to shift under load, accelerate wear on mating surfaces, and create unsafe operating conditions. Replacing a damaged or missing bolt with the correct OEM part restores the designed clamping load and keeps the assembly performing as intended.
