The Multiquip CD2900411 Diaphragm Screw M8 60 is a genuine OEM fastener designed for DM15A9C and CDM2CSA series equipment. As an authentic Multiquip OEM component, it is manufactured to the exact thread pitch, length, and material specification required for secure diaphragm retention. This screw is a direct-fit replacement, confirmed compatible with DM15A9C drill rig stand and CDM2CSA core drill applications. Sourced directly through authorized Multiquip supply channels, the part ensures you are installing the correct hardware the first time.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact M8 thread specification and 60mm length required for proper diaphragm clamping force and sealing integrity.
- Drop-In Installation — Matches the original mounting pattern and thread engagement of the factory diaphragm assembly, requiring no reworking of existing hardware.
- Confirmed Fitment — Compatible with DM15A9C drill rig stand and CDM2CSA core drill models.
- Diaphragm Integrity Protection — Correct clamping torque from a properly sized screw prevents diaphragm distortion, leakage, and premature failure under operating pressure.
- Corrosion-Resistant Construction — Built to withstand the wet and abrasive environments typical of core drilling and drill rig stand operations.
The diaphragm screw secures the diaphragm assembly within the pump or fluid-transfer housing of core drill and drill rig equipment, maintaining the clamping load needed to create a reliable seal between the diaphragm and its mating surfaces. When this screw is worn, incorrectly sized, or missing, the diaphragm cannot seat properly, leading to fluid bypass, pressure loss, and accelerated diaphragm wear. Using the correct OEM fastener — with the right thread, grade, and length — is essential to maintaining consistent hydraulic or pneumatic performance in the system.
