Key Features
- OEM Spring-Load Precision — Manufactured to Husqvarna's exact material grade and wave profile specifications, delivering the correct compression force and load distribution for this specific assembly.
- Direct Drop-In Replacement — Matches the original mounting dimensions and profile, seating correctly without modification across all compatible machines.
- Broad Husqvarna Fitment — Compatible with DMS180 and DMS240 concrete core drill systems, DS150 and DS250 drill stands, and FS513, FS520, and FS524 floor saws.
- Maintains Fastener Clamp Integrity — A properly functioning wave washer sustains consistent clamping load under vibration and thermal cycling, preventing fastener loosening during demanding cutting and drilling operations.
- Genuine OEM Confidence — Sourced directly from Husqvarna, this part meets the same production standards as the component installed at the factory, protecting the integrity of the surrounding assembly.
A wave washer is a thin, corrugated spring element placed beneath a fastener or between mating components to maintain a consistent preload force. In high-vibration equipment such as core drills and floor saws, fasteners can gradually work loose as dynamic loads act on the joint — the wave washer counteracts this by continuously exerting spring pressure that keeps the connection tight. When a wave washer wears flat or fractures, the fastener it supports loses preload, which can lead to component movement, accelerated wear on adjacent parts, and potential structural failure within the assembly.
