Key Features
- Genuine OEM Fastener Grade — Manufactured to the precise thread class and tensile rating specified for MQ Diaphragm Pump assemblies, so clamping force and joint integrity are maintained under operating pressure and vibration.
- Correct Thread Spec: 5/16"-18 x 2 — The UNC thread profile and 2-inch length match the original hardware exactly, allowing this screw to seat and torque properly without thread damage or bottoming out.
- Hex Head with Hex Nut and Lock Washer Configuration — The HN and LW designations confirm this fastener is paired with a hex nut and lock washer, providing the anti-loosening retention critical on vibrating pump equipment.
- Fits MQ Diaphragm Pumps — Confirmed OEM application for the MQ Diaphragm Pump family, making part identification straightforward for technicians servicing this equipment.
- Direct Service Replacement — Drops into the original fastener position without modification, restoring the pump housing or component joint to its designed clamping specification.
A hex screw of this specification serves as a structural fastener in diaphragm pump assemblies, securing housings, covers, or component mounts that must remain tightly joined under continuous vibration and fluid pressure. When a fastener stretches, strips, or corrodes, the joint it holds can loosen, leading to misalignment, leaks, or component separation that takes the pump out of service. Using the correct OEM replacement — with the right thread pitch, length, and hardware pairing — ensures the joint is restored to its original clamping load and keeps the pump operating as designed.
