Multiquip 10382 Shoulder Bolt 3/8 x 3/8 Long

The Multiquip 10382 Shoulder Bolt 3/8 x 3/8 Long is a genuine OEM fastener designed for ride-on power trowel applications across a wide range of Multiquip and Whiteman mechanical trowel models. As an OEM-sourced component, 10382 is manufactured to the exact dimensional and material specifications required by the original equipment design. This bolt fits MD80, HHN, HTN, JWN, and JTO series ride-on power trowels, making it a high-utility fastener for contractors who run mixed fleets of Multiquip finishing equipment. Sourced directly through authorized distribution, this part ships as a verified, application-matched replacement.

Key Features

• Genuine OEM Dimensional Accuracy — Machined to the exact shoulder diameter and length specification (3/8 x 3/8) required for proper seating and load transfer in trowel assemblies.
• Drop-In Installation — Threaded and shouldered to match original bore and fastener positions; installs directly into the trowel frame without re-drilling or modification.
• Broad Trowel Fleet Compatibility — Fits MD80, HHN, HTN, JWN, HHXD5, HHXG5, JTO series, and additional Whiteman and Multiquip ride-on power trowel models.
• Shoulder Design for Controlled Clamping — The precision shoulder provides a fixed bearing surface, preventing over-clamping and maintaining correct pivot or hinge clearance in moving trowel components.
• Structural Integrity Under High-Cycle Operation — Trowel machines operate under continuous rotational load; a correctly spec'd shoulder bolt maintains joint alignment and prevents wear-induced loosening over high-cycle use.

A shoulder bolt differs from a standard hex bolt in that its unthreaded shank — the shoulder — acts as a precision bearing surface or pivot point rather than simply clamping two parts together. In ride-on power trowel assemblies, shoulder bolts are commonly used at pivot joints, linkage connections, and rotating component interfaces where controlled movement and consistent clearance are critical. When a shoulder bolt wears, becomes damaged, or is replaced with an incorrect fastener, joint alignment deteriorates, accelerating wear on adjacent components and introducing unwanted play into the trowel mechanism.
