The Multiquip 2021012 Self Tapping Machine Screws are genuine OEM fasteners designed for Multiquip and STOW diaphragm pump models including D306, MQ-D206H, MQ-D305, SDP-2, and SDP-3. These screws are sourced directly from Multiquip, ensuring the correct thread form, drive type, and material grade for the application. Using the correct OEM fastener keeps critical pump assemblies properly secured without the risk of mismatched threading or premature failure. DHS Equipment supplies this part direct, so you can confirm fitment and order with confidence.
Key Features
- Genuine OEM Fastener Grade — manufactured to the exact thread pitch, head profile, and material specification required by Multiquip for diaphragm pump assemblies.
- Self-Tapping Design — cuts its own mating thread on installation, allowing secure engagement in the pump housing without pre-tapping the bore.
- Broad Diaphragm Pump Compatibility — confirmed fit across MQ and STOW diaphragm pump families, including D306, MQ-D206H, MQ-D305, SDP-2, and SDP-3 models.
- Maintains Pump Integrity — properly torqued OEM screws keep housing panels and covers sealed and aligned, preventing vibration-induced loosening during pump operation.
- Direct Assembly Replacement — replaces worn, stripped, or missing screws in existing pump housing locations using the same part Multiquip specifies at the factory.
Self tapping machine screws are structural fasteners used to secure covers, housings, and panels on diaphragm pump assemblies. Because they form their own thread as they are driven in, they create a tight, vibration-resistant connection in materials that have not been pre-threaded. When screws become stripped, corroded, or lost during service, replacing them with the correct OEM specification is essential — undersized or incorrect thread forms can result in loose panels, misaligned components, and potential fluid exposure during operation.
