- Round Cross Head Profile — The round cross (pan Phillips) head design provides positive driver engagement and even clamping force across pump housing panels and covers.
- Confirmed Fitment for ST4 and ST6 Series — Directly fits ST4, ST6, ST41230, ST41460, ST61230, and ST61460 submersible pump models as a specified OEM component.
- Correct Fastener Torque Integrity — Using the right fastener prevents housing distortion, gasket compression issues, and seal failures that can result from mismatched hardware.
- Direct Assembly Replacement — Replaces fasteners lost or damaged during pump service, teardown, or impeller and housing inspection without requiring substitutions.
A Round Cross M4 Screw is a small-diameter metric fastener used to secure housing panels, covers, and internal components on submersible pump assemblies. Though modest in size, using the correct fastener matters — an undersized or incorrect-grade screw can strip threads, fail to maintain proper clamping load, or allow covers and seals to shift under operating pressure. On submersible pumps like the ST4 and ST6 series, maintaining housing integrity is essential to keeping water out of electrical components and ensuring the pump operates safely and efficiently. Replacing worn or missing hardware with the correct OEM specification screw is a straightforward step that protects the broader pump assembly.
