Multiquip 1718 Bolt 1/4-20 x 1

The Multiquip 1718 is a genuine OEM Bolt 1/4-20 x 1 designed for a wide range of Multiquip and Whiteman equipment, including MQD3HA, MQD2HA, MQD3H, and MQD2H diaphragm pumps, as well as Whiteman walk-behind power trowel models such as J3036H55, HDA-SERIES, B46, BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, B46S90, and the J36-M30 series. As a genuine OEM component sourced directly through Multiquip, part 1718 is manufactured to the exact thread pitch and dimensional specification required for correct installation and secure clamping across all compatible machines. Using the correct fastener matters — mismatched bolts can lead to loose assemblies, vibration-induced failures, and equipment downtime. Order the Multiquip 1718 from DHS Equipment for a direct, verified replacement that installs exactly as the original.

Key Features

• Exact Thread Specification — 1/4-20 x 1 UNC thread form matches OEM torque and clamping requirements precisely, ensuring secure fastening without thread stripping or misalignment.
• Genuine OEM Quality — Manufactured to Multiquip's original material and hardness standards, delivering the same holding strength and corrosion resistance as the bolt that left the factory.
• Broad Fitment Coverage — Confirmed for MQD3HA, MQD2HA, MQD3H, MQD2H diaphragm pumps, and multiple Whiteman walk-behind power trowel series including J-Series, B-Series, HDA-Series, and J36-M30.
• Drop-In Installation — Identical dimensions to the original fastener mean it seats and torques correctly without any drilling, tapping, or hardware modification.
• Prevents Vibration Loosening — A properly spec'd OEM bolt maintains correct clamp load under the continuous vibration typical of trowel and pump operation, protecting surrounding components from wear and fatigue.

A bolt of this specification serves as a structural fastener, clamping components together and maintaining the rigid, aligned assembly needed for the machine to operate safely and efficiently. On diaphragm pumps, fasteners secure housings and valve covers where fluid pressure places constant stress on joints — an incorrect or worn bolt risks leaks or catastrophic housing separation. On walk-behind power trowels, fasteners hold guards, handles, and drive components in place under high-vibration working conditions, and a failed fastener can allow critical parts to shift or detach during operation.
