The Multiquip EM926 Shoulder Screw.375 Dia. x.50 5/16"-18 is a genuine OEM fastener designed for Whiteman and International ride-on power trowels and Multiquip walk-behind trowels and rollers. This part is sourced directly through Multiquip's authorized parts program, ensuring the correct shoulder diameter, thread pitch, and shank length for a proper installation. Verified fitment includes ride-on trowel models HHXDF4, HHXDF5, HHNG5, HHXD5, HHN34TVD, and EHHNK5, as well as walk-behind trowel models JS60C, JH90C, and JH55C, plus V30-W2-LD and V30-W2-R rollers. When replacing fasteners on precision-assembled concrete finishing equipment, using the correct OEM specification part keeps every connected component properly seated and torqued.
Key Features
- OEM-Spec Shoulder Geometry — Manufactured to the exact .375 in. shoulder diameter and .50 in. shoulder length specified for Multiquip trowel and roller assemblies, ensuring correct load-bearing contact at the joint.
- Correct Thread Engagement — 5/16"-18 UNC thread form matches the tapped holes in Whiteman and International ride-on trowel frames and roller components, threading in without chasing or rework.
- Broad Confirmed Fitment — Fits HHXDF4, HHXDF5, HHNG5, HHXD5, HHN34TVD, EHHNK5 ride-on trowels; JS60C, JH90C, JH55C walk-behind trowels; and V30-W2-LD and V30-W2-R walk-behind rollers.
- Structural Fastener Integrity — Shoulder screws carry shear loads at pivot and hinge points; an undersized or worn substitute can allow unwanted movement that affects blade pitch control and trowel balance.
- Genuine OEM Traceability — Sold under part number EM926 and sourced through Multiquip's authorized supply chain, so the material grade and dimensional tolerances match the original build specification.
A shoulder screw is a precision fastener that uses a smooth, accurately machined cylindrical shoulder — rather than full threading — to act as a pivot, spacer, or shear pin within an assembly. On power trowels and walk-behind rollers, shoulder screws are commonly used at pivot points, linkage joints, and guard mounts where a plain bolt would not provide the controlled clearance or load distribution the design requires. When a shoulder screw wears, corrodes, or is replaced with an incorrect substitute, the components it connects can shift, bind, or experience accelerated wear at the mating surfaces.
