Multiquip 10229 Screw HHC 5/16-24 X 1

The Multiquip 10229 Screw HHC 5/16-24 X 1 is a genuine OEM fastener designed for a wide range of Multiquip and Whiteman walk-behind and ride-on power trowels. As an OEM-sourced component, part 10229 is manufactured to the exact thread specification and dimensional tolerances required for correct installation and secure clamping force. This screw fits an extensive lineup of trowel models including BH11C, BH90C, BS90C, JH55C, JH90C, J36, B46, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, and many additional series. Sourcing the correct OEM fastener ensures consistent torque retention and long-term mechanical integrity across service intervals.

Key Features

• Hex Head Cap Fastener Grade — 5/16-24 UNF fine-thread specification delivers superior thread engagement and clamping retention compared to coarser alternatives, critical on vibrating concrete finishing equipment.
• Genuine OEM Part — Sourced directly from Multiquip, ensuring the correct head geometry, thread pitch, and shank length for a drop-in installation without modification.
• Broad Trowel Family Coverage — Fits walk-behind models across J, JA, B, BA, C, CA, HDA, and HPHA/HPLA series, plus ride-on HTX44 series trowels, covering both Whiteman and international variants.
• Vibration-Resistant Thread Integrity — Fine-thread UNF fasteners resist loosening under sustained rotational vibration, helping maintain blade assembly and guard hardware in proper operating position.
• Multi-Application Fastener — Used across trowel blade assemblies, guards, and structural hardware points, making 10229 a practical stock item for crews servicing mixed trowel fleets.

A hex head cap screw is a threaded fastener used to clamp two or more components together with a controlled and repeatable torque value. On power trowels, fasteners like the part are found throughout blade spider assemblies, pitch adjustment hardware, guards, and frame connections where precise thread engagement is essential. When a fastener is the wrong grade, incorrect thread pitch, or is reused past its service life, it can back out under vibration, leading to loosened components, misaligned blades, or hardware loss during operation — all of which affect finish quality and operator safety.
