Multiquip 17985-008 Carriage Bolt 3/8-16 x 1

The Multiquip 17985-008 is a genuine OEM Carriage Bolt 3/8-16 x 1 designed for Whiteman and Essick mixer models including the WM45H, WM45HCE, WM45HE, EM120, and EM12M series. As a direct OEM replacement, this bolt is produced to the same specification as the original hardware, ensuring a proper fit in the exact mounting positions it was engineered for. Sourced directly from Multiquip, part 17985-008 gives you the confidence that comes with using the correct fastener for your mixer. If you need to verify fitment for your specific unit, confirm your model code before ordering.

Key Features

• Correct Thread Form and Length — Manufactured to a 3/8-16 thread specification at 1 inch length, matching the original bolt dimensions exactly as used on compatible Whiteman and Essick mixers.
• Genuine OEM Hardware — Produced to Multiquip's original material and hardness standards, so the bolt head seats flush and the shank holds under the same load conditions as the factory fastener.
• Broad Mixer Compatibility — Confirmed fitment across WM45H, WM45HCE, WM45HE, EM120, and EM12M series concrete and mortar mixers from the Whiteman and Essick families.
• Drop-In Installation — The domed, square-neck carriage bolt design self-locks against the mounting surface during tightening, allowing single-tool installation without a secondary wrench to hold the bolt head.
• Structural Integrity at the Joint — A properly torqued carriage bolt holds mixer components firmly in alignment during drum rotation; a loose or incorrect bolt can allow movement that accelerates wear on surrounding hardware.

A carriage bolt is a fastener with a smooth domed head and a square shoulder beneath it that bites into the material being joined, preventing the bolt from spinning as the nut is tightened. On concrete and mortar mixers, carriage bolts are commonly used to secure panels, guards, handles, and structural frame components that must remain rigidly fixed during continuous drum rotation and vibration. When a carriage bolt wears, corrodes, or is replaced with an incorrect size, the joint it holds can loosen over time, leading to component movement, accelerated wear on adjacent parts, and potential structural failure at the fastener location. Using the correctly specified OEM bolt ensures the joint maintains its clamping force throughout the service life of the machine.
