Key Features
- Genuine OEM Fastener Integrity — Manufactured to Multiquip's exact hardness and dimensional tolerances, ensuring the washer bites and holds under the vibration loads common in compaction, pumping, and rolling equipment.
- Direct Drop-In Installation — Matches the original hole diameter, thread pitch, and seating profile for bolt-on replacement with no fitting or modification needed at the fastener point.
- Broad Cross-Equipment Fitment — A single part number covering concrete pumps, asphalt ride-on rollers, vibratory rollers, track power buggies, trash pumps, and concrete mixers simplifies parts inventory across a mixed fleet.
- Vibration Resistance — Lock washers prevent bolt and nut loosening caused by continuous machine vibration; a missing or worn washer can allow critical fasteners to back out, leading to component shift or structural failure.
- Verified OEM Part Number — Ordering EM923348 directly from an authorized Multiquip distributor like DHS Equipment ensures you receive the correct hardware, not an unverified substitute that may differ in temper or surface finish.
A lock washer is a hardened fastener placed between a nut or bolt head and the mating surface to resist rotational loosening caused by vibration, torque cycling, or dynamic loads. In heavy construction equipment — where engines, hydraulics, and moving assemblies generate constant vibration — even minor fastener loosening can escalate into misalignment, component wear, or sudden failure. Replacing a worn, deformed, or missing lock washer with the correct OEM part restores the clamping integrity of the fastener joint and helps keep the surrounding assembly secure through demanding operating conditions.
