The Multiquip AF0100310100Z Screw 5/16-24x1 Hex SDP-2 is a genuine OEM fastener designed for the STOW SDP-2 diaphragm pump. As an authorized Multiquip OEM part, AF0100310100Z is manufactured to the exact thread pitch, length, and head specification required for proper assembly and sealing on SDP-2 pump components. Using the correct fastener keeps every mating surface properly torqued and prevents fluid leaks, casing distortion, or hardware failure under pump operating pressure. DHS Equipment supplies this part direct, so you can get your SDP-2 back in service with confidence.
Key Features
- Exact Thread Specification — 5/16-24 fine-thread pitch and 1-inch length match the precise fastener spec required at SDP-2 pump assembly points, ensuring correct clamp load without thread stripping.
- Genuine OEM Quality — Manufactured to Multiquip's material and hardness standards for pump fasteners, providing the corrosion resistance and tensile strength needed in wet, high-cycle pump environments.
- Direct Replacement for SDP-2 Pumps — Verified fitment for the STOW SDP-2 diaphragm pump; installs directly into existing threaded bores with no rework or thread chasing required.
- Preserves Pump Integrity — A correctly spec'd fastener maintains consistent clamping force across diaphragm housings and cover plates, preventing pressure loss and premature diaphragm wear.
- Hex Head Drive — Standard hex head design allows quick installation and removal with common wrenches or sockets during routine service and diaphragm replacement intervals.
A hex fastener like the AF0100310100Z plays a critical role in securing pump housings, cover plates, and diaphragm assemblies on the SDP-2 diaphragm pump. When the correct fastener is in place, even clamping force is maintained across sealed surfaces, allowing the diaphragm to flex and move fluid efficiently without leaks. A worn, incorrect, or under-torqued fastener can compromise that seal, leading to fluid bypass, diaphragm damage, or casing failure during operation.
