Multiquip 17985-012 Carriage Bolt 3/8-16 x 1-1/2

The Multiquip 17985-012 is a genuine OEM Carriage Bolt 3/8-16 x 1-1/2 designed for a wide range of Essick and Whiteman mixer models as well as MP masonry saw series equipment. This is a direct OEM replacement sourced through Multiquip's authorized parts network, ensuring the correct thread pitch, shank length, and head geometry for each application it serves. Verified fitment includes Essick mixer models EM70P/S, EM90P/S, EM70SLF, and EM90SLF, Whiteman mixer models WM63E, WM63H5, WM63H8, WM70S/P, WM70SLF, WM70PLF, WM90SLF, WM90PLF, and WM63SLF, as well as MP masonry saw models MP1H, MP115E, MP120E, and MP1455HP. When hardware fails or goes missing, using the correct OEM-spec bolt keeps structural connections secure and eliminates the guesswork of sourcing a substitute.

Key Features

• OEM Thread and Dimensional Accuracy — Manufactured to the exact 3/8-16 thread specification and 1-1/2 inch length required by Multiquip-listed assemblies, ensuring a proper load-bearing connection every time.
• Broad Cross-Equipment Fitment — A single part number covers Essick mixers, Whiteman mixers, and MP masonry saws, making 17985-012 a practical stocking item for mixed fleets.
• Drop-In Installation — The round domed head and square neck of a standard carriage bolt self-locks into most panel and frame holes on these machines, requiring no special tooling to install.
• Structural Connection Integrity — Correct hardware holds mixer drums, guards, and saw components firmly in position under vibration and load cycling — an area where undersized or mismatched bolts frequently back out or strip.
• Genuine Multiquip OEM Part — Supplied directly through the Multiquip authorized parts channel, so material grade and plating match what was originally installed at the factory.

A carriage bolt is a fastener designed to resist rotation at the head while being tightened from the nut end, making it well suited for securing panels, guards, and structural brackets where one-sided access is limited. On mixers and masonry saws, these bolts are commonly used at drum frames, shrouds, and equipment mounting points that experience continuous vibration during operation. A missing, damaged, or incorrect-size bolt in these locations can allow components to shift, create excessive wear on adjacent hardware, or pose a safety concern if a guard or cover works loose during use.
