The Multiquip 17150 Screw 1/4"-20 x 1/2" is a genuine OEM fastener designed for MQD2HA and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this screw matches the exact thread pitch and length specification required for proper assembly on these units. It confirms fitment on both the MQD2HA and MQD3HA models, so you can order with confidence. Using the correct OEM fastener ensures components are secured to the manufacturer's torque and retention requirements — not an approximation.
Key Features
- Exact Thread Specification — 1/4"-20 x 1/2" thread profile matches the original fastener for correct clamping force and engagement depth.
- Genuine OEM Part — Manufactured to Multiquip's original design, ensuring the screw seats and torques correctly without thread stripping or dimensional mismatch.
- Direct Fitment for MQD2HA and MQD3HA — Confirmed for Multiquip MQD2HA and MQD3HA diaphragm pump models with no modification needed.
- Maintains Pump Integrity — A properly fitted fastener keeps pump housings, covers, and internal assemblies sealed and secured during operation, preventing leaks and component movement.
- Part Number Confidence — Ordering by Multiquip part number 17150 eliminates guesswork when sourcing a like-for-like replacement on your pump.
Fasteners like the Multiquip 17150 Screw 1/4"-20 x 1/2" play a critical role in maintaining the structural integrity of diaphragm pump assemblies. They secure housings, end caps, and cover plates that must remain tightly joined under continuous vibration and fluid pressure during pump operation. A worn, damaged, or incorrectly sized screw can allow components to shift or separate, leading to fluid leaks, loss of prime, or accelerated wear on surrounding parts — making replacement with the correct OEM fastener essential to keeping the pump running as intended.
