Multiquip 22465 Hex Head Cap Screw 3/4-16 x 2.5 Gr 8

The Multiquip 22465 Hex Head Cap Screw 3/4-16 x 2.5 Gr 8 is a genuine OEM fastener designed for the STX55J6 and STX55Y6 hydrostatic ride-on power trowels. As a Grade 8 fastener, it delivers the high tensile strength required for the demanding structural and mechanical connections found on heavy-duty finishing equipment. Sourced directly through Multiquip's authorized parts program, part 22465 ensures exact dimensional compliance with the original hardware specification. If you're performing a repair or scheduled service on your STX55 series trowel, replacing worn or damaged hardware with the correct OEM fastener is essential to maintaining the integrity of the assembly.

Key Features

• Grade 8 Tensile Strength — High-grade alloy construction provides the clamping force and shear resistance required for critical fastener positions on ride-on trowel assemblies.
• Exact Thread Specification — 3/4-16 fine-thread pattern and 2.5-inch length match the original hardware exactly, seating and torquing correctly without rework.
• Genuine OEM Quality — Manufactured to Multiquip's original specification, so dimensional tolerances, hardness ratings, and finish meet the same standards as the hardware installed at the factory.
• Confirmed Fitment for STX55 Series — Verified for STX55J6 and STX55Y6 hydrostatic ride-on trowels, eliminating guesswork when sourcing replacement hardware.
• Structural Integrity Under Load — Using the correct grade fastener in load-bearing or vibration-exposed joints prevents bolt fatigue, loosening, and potential assembly failure during operation.

Hex head cap screws are structural fasteners used throughout heavy equipment assemblies to secure components under significant mechanical load, vibration, and torque. The grade rating indicates the fastener's tensile and yield strength — Grade 8 is a high-strength classification suited to demanding joints where under-spec hardware could loosen or fail. On a ride-on trowel like the STX55 series, using the correct fastener in each position is critical; substituting a lower-grade or incorrect-length screw in a load-bearing location can lead to premature loosening, component misalignment, or structural failure during finishing operations.
