Key Features
- Genuine OEM Grade — Manufactured to Husqvarna's exact hardness and thread specifications, so this bolt holds torque values and clamping loads as originally engineered — critical for rotating trowel assemblies.
- Direct Hardware Match — Correct thread form, shank diameter, and head profile for a drop-in installation without modification or substitution.
- CT36 and CT48 Compatibility — Confirmed fitment for both the CT36 and CT48 ride-on power trowels, covering common float and finish troweling configurations.
- Structural Integrity Maintained — Using the correct OEM bolt ensures assembly joints remain properly loaded, preventing loosening or failure during high-vibration troweling operation.
- Verified Part Number — Cross-reference 505821601 against your machine's parts diagram to confirm placement before ordering.
A bolt may be a small component, but in a ride-on power trowel like the CT36 and CT48, fastener integrity is essential to safe and consistent operation. Trowel machines operate under sustained vibration and rotational stress, which places real demands on every fastener in the assembly. Using an incorrect or substandard bolt in these applications risks joint failure, component misalignment, or damage to surrounding hardware — making an exact OEM replacement the only sound choice for a proper repair.
