The Multiquip 176600700 is a genuine OEM 7/16"-14 x 2" LG Socket Set Screw designed for MQD2HA and MQD3HA diaphragm pumps. As a direct OEM replacement, this set screw meets Multiquip's original specifications, ensuring a correct and secure fit in the application it was engineered for. Sourced directly through an authorized Multiquip parts channel, 176600700 is the right call when you need confidence that the hardware will perform the way the machine was built to expect. Verify your model against the MQD2HA and MQD3HA fitment before ordering to confirm compatibility.
Key Features
- OEM-Spec Threading and Engagement: — Cut to the exact 7/16"-14 thread pitch and 2" length specified by Multiquip, ensuring full thread engagement and proper clamping force in the intended bore.
- Drop-In Hardware Replacement: — Matches the original fastener geometry exactly, so installation requires only a standard hex key with no re-tapping or modification to the mating component.
- Confirmed Fitment for MQD Diaphragm Pumps: — Verified for use on MQD2HA and MQD3HA diaphragm pump models, giving you a clear part-to-machine match before the order is placed.
- Maintains Secure Component Retention: — A properly torqued set screw holds shafts, collars, or fittings in precise position; a worn, stripped, or undersized screw can allow critical components to shift under pump vibration and pressure cycles.
- Genuine OEM Part: — Supplied as an authentic Multiquip replacement, meaning the material grade and dimensional tolerances are identical to the fastener that left the factory with the machine.
A socket set screw is a headless fastener tightened by a hex key into a threaded bore, using its tip to bear against — or bite into — a mating shaft or surface to lock a component firmly in place. On diaphragm pumps like the MQD2HA and MQD3HA, set screws are used to secure rotating or stationary assemblies against axial and rotational movement caused by pump cycling. When a set screw loosens, backs out, or strips, the retained component can shift, leading to misalignment, accelerated wear, or outright mechanical failure that takes the pump out of service.
