Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact material and dimensional specifications, ensuring the correct hardness and surface finish needed for consistent clamping force in floor grinder assemblies.
- Exact-Match Replacement — This washer installs directly in place of the original, maintaining proper load distribution across fastener joints without shimming or adjustment.
- Broad HTC Floor Grinder Compatibility — Fits the HTC270EG, HTC1500, HTCXP6, HTCGL270, HTC420VS, HTC800RXP, HTC400DS, and HTC950RX floor grinders.
- Protects Mating Surfaces — A properly fitted washer prevents fastener pull-through and surface damage, preserving the integrity of the surrounding components in high-vibration grinding applications.
- Simple Service Component — Small in size but critical to assembly integrity — replacing a worn or deformed washer restores correct torque retention and prevents loosening during operation.
A washer serves as the load-distributing interface between a fastener and the surface it secures. In floor grinders like the HTC series, where continuous vibration and rotational forces are present, washers prevent fastener loosening, protect softer mating surfaces from damage, and help maintain consistent clamping pressure over time. When a washer becomes deformed, corroded, or worn, fasteners can back out under vibration or cause surface damage that complicates future servicing — making timely replacement an important part of maintaining the machine's overall assembly integrity.
