Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact 1/4-20 thread specification, ensuring full engagement with mating hardware and eliminating the risk of cross-threading or loose connections.
- Correct Length for Direct Installation — The 3-inch length matches the original fastener spec, allowing the bolt to seat properly without shimming, trimming, or adaptation.
- Confirmed Fitment for MQD2HA and MQD3HA — Verified for Multiquip MQD2HA and MQD3HA diaphragm pump models, so you can order with confidence.
- Maintains Pump Structural Integrity — A correctly torqued, properly sized bolt keeps pump housings, covers, and mounting points secure under the vibration and pressure cycles these machines produce during operation.
- OEM Sourced Reliability — Using the correct OEM fastener protects the threads in the receiving component, extending the service life of surrounding hardware and the pump assembly itself.
A hex bolt may be a small component, but in a diaphragm pump it plays a critical role in holding housings, valve plates, and cover assemblies under constant pressure and vibration. An incorrect bolt — wrong length, wrong thread pitch, or insufficient grade — can work loose or strip the receiving threads, leading to fluid leaks, pump inefficiency, or accelerated wear on surrounding components. Using the correct OEM-spec fastener like the Multiquip 173401300 ensures every bolted joint on your MQD2HA or MQD3HA maintains the clamping force it was designed to hold throughout the service interval.
