The Multiquip EF410062 Jam Nut 5/8-18 UNF SDP-2 is a genuine OEM fastener designed for the STOW SDP-2 diaphragm pump. As an authentic Multiquip part, it meets the exact threading and dimensional specifications required for a correct, secure installation on SDP-2 series equipment. Confirm your model against the SDP-2 fitment reference before ordering to ensure compatibility.
Key Features
- Correct Thread Specification — 5/8-18 UNF thread form matches the factory-specified fastener standard for SDP-2 diaphragm pump assemblies, ensuring proper engagement and secure locking.
- Genuine OEM Construction — Manufactured to Multiquip's material and hardness standards, delivering the torque retention and corrosion resistance expected in pump service environments.
- Direct-Fit Replacement — Engineered to install in the same position as the original fastener on SDP-2 units, requiring no thread chasing or rework to adjacent components.
- SDP-2 Diaphragm Pump Fitment — Confirmed compatibility with the STOW SDP-2 diaphragm pump series; cross-reference EF410062 with your parts list before purchasing.
- Locking Security Under Vibration — Jam nut profile provides a secondary locking function against a primary nut or fitting, maintaining clamp load during pump operation where vibration could otherwise cause loosening.
A jam nut is a thin fastener threaded against a primary nut or threaded component to lock it in position and prevent it from backing off during operation. On a diaphragm pump like the SDP-2, vibration generated during pumping cycles can gradually loosen standard fasteners — the jam nut counteracts this by creating opposing clamping forces that keep the assembly tight. A missing, damaged, or incorrect jam nut can result in loosening of the secured component, leading to leaks, misalignment, or accelerated wear on surrounding parts.
