Key Features
- Genuine OEM Hardness and Temper — Manufactured to Husqvarna's material specifications, this lock washer delivers the correct tension and bite needed to hold fasteners securely under the vibration loads typical of floor grinding equipment.
- Drop-In Hardware Replacement — Dimensioned to match the original fastener stack exactly, this washer seats and locks without modification to adjacent bolts, studs, or housings.
- Broad Grinder and Dust Equipment Fitment — Compatible with HTC80, HTCD60, HTCD80, PG540, PG830S, DURATIQT5, and several other floor grinder and dust equipment models in the Husqvarna lineup.
- Prevents Fastener Back-Out — A correctly functioning lock washer keeps critical fasteners torqued in place during operation; a failed or missing one allows vibration to loosen connections, which can lead to misalignment or component damage.
- Verified Part Number Cross-Reference — Cross-reference part number 593511101 against your machine's parts diagram to confirm the correct position and quantity before ordering.
A lock washer is a hardened fastening component that sits between a bolt or nut and the mating surface to resist loosening caused by vibration and dynamic loads. In floor grinders and surface preparation equipment, where grinding heads generate continuous rotational forces, lock washers play a critical role in keeping assembly fasteners secure throughout operation. When a lock washer becomes deformed, corroded, or lost during service, the fastener it supports can work loose over time, compromising the integrity of the assembly it holds together.
