The Multiquip 43354 Shoulder Screw M10 X M20 X M8-1.25 is a genuine OEM fastener designed for STXDF series ride-on power trowels. As a direct Multiquip OEM component, part 43354 is manufactured to the exact dimensional tolerances required for proper installation in the STXDF dual-fuel hydrostatic trowel platform. Sourced directly through authorized Multiquip distribution, this shoulder screw is a verified fit replacement that keeps your machine operating as intended.
Key Features
- OEM-Grade Thread and Shoulder Tolerancing — Manufactured to exact M10 x M20 x M8-1.25 specifications, ensuring the shoulder seats correctly and the threaded portion engages with proper torque characteristics.
- Drop-In Installation — Matches the original fastener geometry exactly, so no reworking of mounting holes or mating hardware is needed during installation.
- Confirmed Fitment for STXDF Trowels — Verified for Whiteman STXDF super-sized hydrostatic ride-on trowels, eliminating guesswork when sourcing replacement hardware.
- Structural Integrity Under Load — Shoulder screws carry both shear and alignment loads in trowel assemblies; an out-of-spec or worn fastener can cause component misalignment and accelerated wear on mating parts.
- Genuine Multiquip OEM Part — Part number 43354 is supplied directly through authorized Multiquip channels, ensuring the correct grade, finish, and dimensional accuracy for the application.
A shoulder screw is a precision fastener that uses a machined, unthreaded shoulder to serve as a bearing surface, pivot point, or alignment guide for moving or mating components. Unlike a standard bolt, the shoulder — not the thread — bears the primary load, making exact diameter and length critical to correct function. When a shoulder screw is worn, incorrect, or improperly seated, it can cause excessive play, misalignment of linked components, and premature wear to the surrounding assembly.
