The Multiquip 3058032 is a genuine OEM Flat Head Machine Screw 8-32 NC 1/2" designed for MQ-D305 and D306 diaphragm pump equipment. As an authentic Multiquip OEM component, it is manufactured to the exact thread pitch, drive, and dimensional spec required for correct installation. This screw is confirmed for use on MQ-D305 and D306 series diaphragm pumps, ensuring a straightforward, exact-fit replacement. Keeping the correct fasteners in service on your pump housing prevents fastener failure, stripped threads, and potential fluid leaks under operating pressure.
Key Features
- Genuine OEM Thread Accuracy — Manufactured to the exact 8-32 NC thread specification, eliminating the risk of cross-threading or improper engagement in tapped pump housing bores.
- Correct Head Profile — Flat head geometry seats flush with mating surfaces, maintaining proper clamp load and preventing interference with adjacent pump components.
- Direct OEM Replacement — Drop-in fitment for MQ-D305 and D306 diaphragm pumps with no rework or thread chasing required when replacing a like-for-like fastener.
- Confirmed Diaphragm Pump Fitment — Verified for MQ-D305 and D306 series, so you can order with confidence that the part is correct for your machine.
- Structural Integrity Under Pressure — A correctly sized and properly torqued fastener maintains housing and cover alignment on a diaphragm pump, supporting consistent seal compression and leak-free operation.
A machine screw is a precision fastener used to clamp pump housings, covers, and diaphragm assemblies together in fixed, repeatable alignment. On a diaphragm pump, fastener integrity is directly tied to seal performance — a stripped, incorrect, or overtorqued screw can compromise the clamping force that keeps the diaphragm seated, leading to pressure loss or fluid bypass. Replacing worn or damaged fasteners with the correct OEM part restores proper torque capacity and keeps the pump assembly operating as designed.
