Multiquip 10229 HHCS 5/16-24 X 1

The Multiquip 10229 HHCS 5/16-24 X 1 is a genuine OEM hex head cap screw designed for Whiteman and International walk-behind power trowels and HTX44 series ride-on trowels. As a factory-sourced fastener, it matches the exact thread pitch, grip length, and head dimensions specified for these machines, ensuring a secure, correctly torqued connection wherever it is installed. Compatible models include HDA Series, JS60C, JH90C, JH55C, BS90C, BH11C, BH90C, CA4HC, CA5BC, B46, CA4HM, J3036H55, J36-M30, BS46H11, BS46H90, HTX44Y5, HTX44Y4, HTX44K5, HTX44K4, CA4H, B Series, JS36H90, JS36H55, CS24H55E, and B46S90. Sourcing the correct OEM fastener by part number 10229 keeps your trowel assembled to specification and avoids the fitting issues that come with generic hardware substitutions.

Key Features

• Genuine OEM Thread Specification — 5/16-24 fine-thread pitch and 1-inch grip length match the exact fastener spec called out in Multiquip service documentation, ensuring full thread engagement and proper clamp load.
• Drop-In Fitment Across Multiple Trowel Families — Installs directly in place of the original hardware on HDA Series, J36, B46, CA Series, BS Series, JH Series, and HTX44 models without modification.
• Wide Model Coverage — A single part number covers walk-behind trowels including JS60C, JH55C, BH90C, BS46H11, and BS46H90, as well as ride-on models HTX44Y4, HTX44Y5, HTX44K4, and HTX44K5.
• Structural Integrity Where It Counts — Trowel frames and blade assemblies rely on correctly sized fasteners to maintain alignment under continuous vibration; an undersized or mis-threaded bolt can allow components to shift during operation.
• OEM Sourcing for Accurate Replacement — Ordering by Multiquip part number 10229 eliminates the guesswork of matching hardware store equivalents against thread class, length, and head size simultaneously.

A hex head cap screw is a standard threaded fastener used to clamp and secure mechanical assemblies — in this case, structural and drive components on Whiteman and International power trowels. The fine 5/16-24 thread pitch provides greater clamping force per unit of torque compared to a coarse-thread fastener of the same diameter, making it well suited to high-vibration environments like concrete finishing equipment. When a fastener of this type is missing, stripped, or replaced with an incorrect substitute, the joined components can loosen progressively during use, leading to misalignment, accelerated wear on adjacent parts, or mechanical failure.
