Multiquip 22022 Hex Flange Screw M8-1.25 x 90MM GR 10.9

The Multiquip 22022 is a genuine OEM Hex Flange Screw M8-1.25 x 90MM GR 10.9 designed for Whiteman hydrostatic ride-on power trowels. This high-grade 10.9 metric fastener is sourced directly from Multiquip and built to the exact specification required for these machines. Confirmed fitment includes the HTX44Y4, HTX44Y5, and LD60 models. Keeping the correct OEM hardware in place ensures structural integrity and consistent torque performance across critical assembly points.

Key Features

• Grade 10.9 High-Strength Rating — The 10.9 grade designation means this fastener delivers high tensile and proof-load strength, making it suitable for the high-stress clamping applications found on ride-on trowel assemblies.
• M8-1.25 x 90MM Hex Flange Profile — The integrated flange distributes clamping load over a wider bearing surface without a separate washer, allowing direct installation into the mating points it was engineered for.
• Genuine OEM Multiquip Part — Part number 22022 is sourced directly from Multiquip, matching the original hardware specification to the thread pitch, length, and grade used during assembly.
• Verified Fitment for HTX44Y4, HTX44Y5, and LD60 — Confirmed for these Whiteman hydrostatic ride-on trowel models, so you can order with confidence that this screw is the correct replacement for your machine.
• Prevents Fastener Failure at Critical Joints — Using the correct grade fastener prevents under-clamping or hardware fatigue, which can lead to loosening, component movement, or structural damage over time.
• Safety-Critical Hardware Compliance — On ride-on trowels, fastener integrity at key structural and drivetrain points directly affects operator safety — substituting a lower-grade fastener risks joint failure under load.

A hex flange screw combines a standard hex head with an integrated flange that acts as a built-in washer, spreading the clamping force across a larger surface area and helping to prevent pull-through or surface damage on assembled components. The M8-1.25 thread pitch and 90MM length are specific to the mating geometry of the assembly it fastens, meaning the correct part is essential for achieving proper torque and clamp load. When a fastener of the wrong grade or length is used, it can work loose under vibration, cause misalignment of connected components, or fail entirely — all of which can lead to equipment damage or a safety hazard on the job.
