Key Features
- Genuine OEM Material Spec — Manufactured to the exact hardness and thickness tolerances required for secure locking performance in Multiquip assemblies.
- Thread-Matched Sizing — The 1/16-14 specification ensures a flush, correctly tensioned seat against mating fasteners without slippage or over-compression.
- Broad Cross-Family Fitment — Confirmed for EM12M series Essick mixers and MP1455HP, MP120E, MP115E, and MP1H masonry saws — one part across multiple equipment families.
- Prevents Fastener Back-Out — A properly functioning lock washer maintains clamping force under vibration; a worn or missing washer allows fasteners to loosen and can lead to component misalignment or failure.
- Direct OEM Source — Supplied as a genuine Multiquip replacement, so the part integrates into existing hardware configurations exactly as the original did.
A lock washer is a small but critical fastener component placed beneath a nut or bolt head to resist loosening caused by vibration and operational movement. By biting into both the fastener and the mating surface, the lock washer maintains clamping load over time. In equipment like mixers and masonry saws — where consistent vibration is a normal part of operation — a failed or missing lock washer can allow fasteners to back out, leading to loose assemblies, misaligned components, or accelerated wear on surrounding hardware. Replacing worn or damaged lock washers during routine service is a simple step that protects the integrity of the broader assembly.
