Key Features
- OEM-Spec Thread and Head Profile — M5 x 20 dimensions and round cross-head profile match original assembly specs exactly, so drive engagement and clamping torque are consistent with the factory build.
- Direct Drop-In Replacement — Threads straight into existing bosses and mounting points on ST1 and ST1F submersible pumps with no rework or re-tapping required.
- Fits ST1 and ST1F Submersible Pumps — Verified OEM fitment for Multiquip ST1 and ST1F models; cross-reference part number 2730243203 against your service manual before ordering.
- Corrosion-Resistant Hardware Grade — Genuine OEM fastener material is selected for the wet, submerged operating environment of submersible pump applications, supporting long service life in demanding conditions.
- Maintains Structural Integrity of the Assembly — Using the correct fastener prevents stripped threads, housing misalignment, and seal compression issues that can result from substituting an incorrect-size screw.
A round cross screw is a threaded fastener that secures pump housing panels, guards, or internal components together using a Phillips-style cross-head drive. In a submersible pump, fasteners like this one are critical to maintaining proper casing alignment and ensuring that seals compress evenly — both of which directly affect whether the pump remains watertight under operating pressure. When a screw is damaged, corroded, or substituted with an incorrect size, it can lead to loose assemblies, seal failures, or stripped mounting bosses that compromise the pump's performance and service life.
