The Husqvarna 593509101 Screw is a genuine OEM fastener designed for the PG-series and HTC1500 floor grinders, including the PG690, PG830, PG540, PG8XR, PG8DR, PG8D, PG8P, PG8S, PG6S, PG5, PG690RC, PG690P, PG830RC, PG830P, PG830S, and HTC1500. As a direct Husqvarna OEM component, this screw is manufactured to the exact thread specification, head geometry, and material grade called out in the original assembly. Correct fastener specification is critical on floor grinders, where vibration and load cycles demand hardware that holds torque without loosening or stripping. DHS Equipment supplies this part to help keep your equipment running at full performance.
Key Features
- OEM Thread and Material Specification — manufactured to Husqvarna's exact thread pitch, head type, and material grade, ensuring the fastener performs under the vibration loads typical of planetary floor grinders.
- Drop-In Assembly Fit — matches the original hole pattern and drive type precisely, so installation requires no reworking of mating components or thread repair.
- Broad PG-Series Compatibility — confirmed for PG690, PG830, PG540, PG8-series, PG5, PG6S, HTC1500, and their RC and P variants; cross-reference part number 593509101 against your parts diagram to verify the correct position.
- Structural Integrity Under Load — a correctly specified screw maintains clamp force across components during grinding passes; a worn, stripped, or incorrect fastener can allow movement that damages housings, guards, or drive assemblies.
- Genuine Husqvarna OEM Part — sourced directly from Husqvarna's construction equipment parts program, giving you confidence that the replacement matches what left the factory.
A screw in a floor grinder assembly does more than hold components together — it maintains the precise clamping force needed to keep plates, guards, drive components, and housings aligned and secure through continuous vibration and load. When a screw stretches, strips, or is substituted with an incorrect fastener, it can allow micro-movement between mating parts, accelerating wear on surrounding components and potentially creating a safety risk. Replacing a damaged or lost fastener with the correct OEM specification screw restores the assembly to its designed clamping integrity and prevents further damage.
