The Husqvarna 594977001 Hex Nut 5/8-11 UNC G5 Nyloc is a genuine OEM fastener designed for the CRT36I power trowel. As an OEM component, this nut is manufactured to Husqvarna's exact dimensional and material specifications, ensuring a true drop-in fit with no guesswork at the fastener level. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Grade 5 Nyloc Construction — The nylon-insert locking collar holds thread engagement under vibration, which is critical on power trowel assemblies subject to constant cyclical loading.
- Correct Thread Specification — Cut to 5/8-11 UNC thread form, this nut engages mating hardware precisely without risk of cross-threading or improper torque transfer.
- Genuine OEM Sourced — Supplied directly from Husqvarna's parts program, this fastener meets the same material grade and dimensional tolerance as the hardware originally installed at the factory.
- CRT36I Power Trowel Fitment — Confirmed fit for the CRT36I ride-on power trowel; cross-reference part number 594977001 against your parts diagram to verify the correct fastener position before ordering.
- Vibration-Resistant Locking — The Nyloc design prevents self-loosening during operation, reducing the risk of fastener failure and the structural issues that can follow on high-cycle finishing equipment.
A hex nut is a fundamental fastener that clamps and secures mating components together by converting rotational torque into clamping force along a threaded bolt or stud. On power trowels like the CRT36I, fasteners are exposed to sustained vibration from the rotating trowel blades and engine, making a locking fastener — such as this Nyloc design — essential for maintaining joint integrity over extended use. A missing, stripped, or incorrect-grade nut can allow critical assemblies to loosen during operation, leading to misalignment, accelerated wear on surrounding components, or unsafe machine conditions.
