Key Features

• Exact OEM Dimensions — Precision-machined to 3/8 x 3/8 shoulder specification, ensuring the bolt seats correctly within the trowel frame and pivot points without play or misalignment.
• Genuine Multiquip Part — Manufactured to the same tolerances as the original hardware, maintaining the structural integrity of critical trowel assembly connections.
• Broad Trowel Series Compatibility — Fits MD80, HHN, HTN, and JWN series ride-on power trowels, covering both Multiquip and Whiteman mechanical and hydrostatic models.
• Direct Drop-In Replacement — Matches the original mounting configuration, allowing straightforward installation with standard tooling and no modification to the surrounding hardware.
• Maintains Fastener Integrity — A worn or incorrect shoulder bolt in a trowel assembly can introduce unwanted movement at pivot connections, leading to uneven blade pitch and poor surface finish results.

A shoulder bolt is a precision fastener with a smooth, unthreaded cylindrical shank between the head and the threaded section. In ride-on power trowel assemblies, shoulder bolts are commonly used at pivot points and linkage connections where parts must rotate or articulate around the bolt body. The smooth shank acts as a bearing surface, controlling movement while keeping components properly aligned. When a shoulder bolt wears, corrodes, or is replaced with an incorrect fastener, pivot points lose their defined motion, which can result in inconsistent blade pitch, vibration, and an uneven concrete finish.
