Key Features
- Exact Thread Specification — 1/2"-13 UNC thread profile and 1-1/2" length match the OEM fastener spec for secure clamping force on diaphragm pump assemblies.
- Genuine OEM Hardware — Manufactured to Multiquip's material and hardness standards, so you get consistent torque performance without risk of stripping or failure under pump vibration.
- Direct SDP-2 Fitment — Confirmed replacement for the STOW SDP-2 diaphragm pump; installs in the same position as the original without rework or modification.
- Leak-Prevention Critical — Properly torqued fasteners are essential to maintaining diaphragm clamp integrity; using the correct hex screw helps prevent fluid weeping and premature diaphragm wear.
- Hex Drive for Easy Torquing — Standard hex head allows use of common wrenches and torque tools, making installation and future service straightforward in the field.
A hex screw like the AO100500150 plays a critical role in diaphragm pump assemblies by clamping the diaphragm housing sections together under controlled torque. In a diaphragm pump, the fasteners that secure the pump body must maintain consistent clamping load to prevent fluid bypass, housing separation, and accelerated diaphragm wear. When a fastener is the wrong size, under-torqued, or worn, it can allow the diaphragm clamp faces to shift or weep — compromising pump efficiency and potentially causing unplanned downtime in dewatering or fluid transfer operations.
