• Correct 5/16-18 Thread Specification — Matches the original thread pitch and profile exactly, seating and torquing as intended without rework or modification to existing threaded components.
• Broad Trowel Family Coverage — Fits HHN, HTN, JWN, J Series, JA Series, B Series, BA Series, C Series, CA Series, and numerous Whiteman and international walk-behind and ride-on trowel models.
• Maintains Secure Clamping Force — A properly installed jam nut locks adjustment positions and prevents fastener loosening under the continuous vibration loads generated during troweling operations.
• Verified Multiquip OEM Part Number — Part number this part is the exact reference used in Multiquip service documentation, eliminating guesswork when ordering replacement hardware.

A jam nut is a thin secondary nut threaded against a primary nut or fastener to lock it in position and prevent it from backing out during machine operation. On power trowels, jam nuts are used at adjustment points throughout the blade and pitch control linkage where vibration would otherwise cause standard fasteners to loosen over time. When a jam nut fails, strips, or goes missing, the fastener it secures can lose its set position, leading to inconsistent blade pitch, uneven finishing, or mechanical play in the linkage. Replacing a worn or damaged jam nut promptly restores the integrity of the connection and keeps blade adjustments holding true across a full day of use.
