Multiquip 10181 HHC Screw 5/16-24 x 1-1/4

The Multiquip 10181 is a genuine OEM HHC Screw 5/16-24 x 1-1/4 designed for a wide range of Multiquip and Whiteman walk-behind and ride-on power trowel models. As an authentic Multiquip replacement fastener, part 10181 is manufactured to the same specifications as the original hardware, ensuring a correct and secure fit wherever it is used in the assembly. This screw is confirmed to fit J-Series, JA-Series, JS-Series, B-Series, BA-Series, CA-Series, M30H55, HTXD6i, HTXG6DF, and STXD6i trowels, covering both domestic and international configurations. Sourcing the correct OEM fastener keeps critical connections tight and prevents the loosening or mechanical failure that can result from using an incorrect grade or thread pitch.

Key Features

• Correct Thread Specification: — 5/16-24 fine-thread pitch matches the original tapped receiver exactly, preventing cross-threading and ensuring full clamping force.
• Genuine OEM Hardware: — Authentic Multiquip part 10181, produced to the same material grade and dimensional tolerance as the factory-installed fastener.
• Broad Trowel Compatibility: — Fits J-Series, JA-Series, JS-Series, B-Series, BA-Series, CA-Series, HTXD6i, HTXG6DF, and STXD6i walk-behind and ride-on power trowels.
• Secure Assembly Integrity: — Correct fastener grade maintains proper clamp load across trowel components, preventing vibration-induced loosening during operation.
• Direct OEM Sourced Replacement: — Replaces the original fastener on a one-for-one basis with no re-drilling, re-tapping, or hardware modification needed.

A hex head cap screw like the Multiquip 10181 serves as a primary structural fastener within power trowel assemblies, securing components such as guards, housings, and mechanical linkages that must remain firmly fixed during high-vibration operation. Using a fastener with the correct thread pitch, grip length, and head configuration is critical — an undersized or incorrect-grade screw can back out under load or strip the receiving thread, leading to loose components and potential hazard during use. Replacing worn or damaged fasteners with the correct OEM specification hardware restores the mechanical integrity of the joint and keeps the trowel operating as intended.
