The Multiquip 20179 is a genuine OEM HHC Screw 3/4-16 x 2" Grade 8 designed for HTX44 and STX55 series hydrostatic ride-on power trowels. As a certified OEM component, this fastener is manufactured to the same specifications as the original hardware installed at the factory, ensuring correct torque capacity and dimensional accuracy for your machine. Verified fitment covers the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55Y6, and STX55J6 models. Sourcing the correct grade-rated fastener keeps structural connections secure and helps maintain the integrity of critical assemblies on your trowel.
Key Features
- Grade 8 Tensile Strength — High-strength 3/4-16 threading and Grade 8 rating deliver the clamping force required for heavy-duty trowel structural connections.
- Genuine OEM Component — Sourced directly from Multiquip, this fastener matches the original part installed on the production line — exact thread pitch, length, and grade specification.
- Confirmed Fitment for HTX44 and STX55 Series — Directly compatible with HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55Y6, and STX55J6 hydrostatic ride-on power trowels.
- Drop-In Hardware Replacement — The 3/4-16 x 2" dimensions align with existing bores and fastener pockets — no reworking of mounting points needed during installation.
- Structural Integrity Assurance — A correctly rated fastener prevents loosening under the vibration and load cycles typical of ride-on trowel operation; an underrated or incorrect substitute risks joint failure during use.
A hex head cap screw like the Multiquip 20179 serves as a primary structural fastener, securing major assemblies and load-bearing connections on the machine. The Grade 8 designation indicates a minimum tensile strength significantly higher than standard hardware, making it suited to the high-vibration environment of a hydrostatic ride-on trowel. When a fastener of the wrong grade or thread specification is used in its place, it can stretch, strip, or fail under operational load — compromising the safety and performance of the trowel and the assemblies it holds together.
