The Multiquip 10990 Shoulder Bolt 1/4 X 1/4 NP is a genuine OEM fastener designed for JTO-SERIES Whiteman ride-on power trowels. As a direct Multiquip OEM component, 10990 is manufactured to the exact dimensions and material specifications required by the original equipment design. This shoulder bolt is a precision fastener where the unthreaded shank diameter and length are held to tight tolerances — making an exact match essential for correct function. Confirm your model against the JTO-SERIES fitment before ordering to ensure compatibility.
Key Features
- Precision-Dimensioned Shoulder: — The 1/4 x 1/4 shoulder shank is held to strict dimensional tolerances, ensuring the bolt seats and pivots correctly in applications where the unthreaded portion carries load or controls spacing.
- Genuine OEM Construction: — Sourced directly from Multiquip, this fastener matches the original hardness grade, shank diameter, and thread specification called out in the factory bill of materials.
- Direct-Fit for JTO-SERIES Trowels: — Engineered specifically for JTO-SERIES Whiteman ride-on power trowels; installs in the original position without alteration or shimming.
- Maintains Pivot and Alignment Integrity: — A worn or undersized shoulder bolt introduces play into pivoting assemblies, leading to uneven blade pitch and accelerated wear on surrounding components. A correctly sized OEM replacement restores tight, accurate movement.
- Verified Part Number: — Order by Multiquip part number 10990 to ensure you receive the correct shoulder bolt length, shank diameter, and thread configuration for your machine.
A shoulder bolt differs from a standard fastener in that its precision-ground unthreaded shank — not the threads — does the primary mechanical work. The shoulder acts as a pivot pin, spacer, or locating element, controlling the movement and alignment of the components it connects. On ride-on power trowels, these bolts are commonly used in blade pitch linkages and control assemblies where consistent geometry directly affects finishing quality. When the shoulder wears or the bolt is replaced with an incorrect size, pivot points develop slop, blade angles become inconsistent, and the trowel's finish output suffers.
