The Multiquip A0100500250 is a genuine OEM Hex HN Screw 1/2" x 2-1/4" designed for the SDP-2 STOW diaphragm pump. As a direct OEM replacement, this fastener is sourced to the exact specification Multiquip engineers built into the original machine, ensuring a correct and secure fit every time. This hardware is manufactured to match the thread pitch, head geometry, and material grade of the original screw used on SDP-2 equipment. Whether you are performing routine maintenance or restoring a pump after service, part number A0100500250 keeps your diaphragm pump assembled to its original mechanical integrity.
Key Features
- OEM-Grade Fastener Spec — Manufactured to the exact thread pitch, diameter, and head dimensions specified for SDP-2 diaphragm pump assemblies, not a generic hardware substitute.
- Direct-Fit Hardware — Engineered to drop straight into the SDP-2 mounting points with no modification to hole spacing or torque specification required.
- Confirmed SDP-2 Fitment — Verified for use on the STOW SDP-2 diaphragm pump series; always cross-reference part number A0100500250 before ordering.
- Structural Clamping Integrity — A correctly torqued fastener of this type maintains housing seal compression on diaphragm pumps; a worn, stripped, or undersized screw can allow housing separation and immediate pump failure.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain and sold by DHS Equipment, an authorized distributor.
The Hex HN Screw 1/2" x 2-1/4" is a structural fastener used to secure housing panels, pump body sections, or cover assemblies on the SDP-2 diaphragm pump. On a diaphragm pump, maintaining correct clamping force across housing joints is critical — these screws hold internal components under the cyclical pressure loads the pump generates during operation. When a fastener of this type becomes stripped, corroded, or missing, the housing can shift or separate, compromising the pump's ability to maintain prime and allowing fluid leaks that damage internal components and create safety hazards on the worksite.
