The Multiquip A0100370150 Hex Bolt 3/8" x 1-1/2" is a genuine OEM fastener designed for the STOW SDP-2 diaphragm pump. As an OEM-sourced component, this bolt is manufactured to the exact size, thread pitch, and grade specification called for in the SDP-2 assembly, ensuring a correct and secure fit every time. DHS Equipment supplies this part direct, so you can be confident you are receiving the same bolt that left the factory. Whether you are completing a routine service or a field repair on your SDP-2, having the correct fastener on hand keeps the job moving.
Key Features
- Correct Grade and Dimensions — 3/8" diameter by 1-1/2" hex head bolt matched to the exact thread specification used in STOW diaphragm pump assemblies.
- Genuine OEM Sourcing — Manufactured to the same tolerances as the original hardware, maintaining proper clamp load and joint integrity at all fastened connections.
- Direct Replacement for SDP-2 — Confirmed fitment for the STOW SDP-2 diaphragm pump; installs in place of the original bolt without modification.
- Structural Integrity at Every Connection — A correctly sized and graded bolt prevents joint loosening, pump housing leaks, and premature wear at mating surfaces caused by undersized or off-spec fasteners.
- Critical for Fluid-Containment Assemblies — In diaphragm pump applications, fastener integrity is directly linked to leak-free operation; using the specified OEM bolt supports consistent sealing performance across pump cover and valve assemblies.
A hex bolt in a diaphragm pump assembly does more than hold components together — it applies and maintains the clamping force needed to compress gaskets and seals across pump housings, valve covers, and fluid chambers. If a bolt is the wrong length, thread pitch, or grade, it can strip threads, fail to seat properly, or allow internal pressure to bypass sealing surfaces. On the STOW SDP-2, using the correct A0100370150 specification fastener ensures that every bolted joint in the pump maintains the clamping load required for leak-free, reliable operation over repeated pump cycles.
