The Wacker Neuson Socket Hex Bolt is a genuine OEM fastener designed for the PS3-5503, PS4-5503, PS4-7503HH, and PS4-7503HF series submersible pumps. As a factory-sourced component, it is manufactured to the exact material grade and thread specification required by the original pump design. This bolt is used across the full range of PS-series submersible pump configurations, covering 3-inch and 4-inch discharge models in both 50Hz and 60Hz variants. Confirming the correct part number before ordering ensures a direct, trouble-free installation.
Key Features
- Genuine OEM Material Grade — Sourced directly from Wacker Neuson, this socket hex bolt meets the exact tensile strength and thread specification required to safely secure pump housing components under continuous submersed operating loads.
- Direct Drop-In Installation — Machined to the original thread pitch and head dimensions, this bolt seats and torques correctly without modification, maintaining the integrity of the pump assembly.
- Broad PS-Series Compatibility — Fits PS3-5503, PS4-5503, PS4-7503HH, and PS4-7503HF submersible pump models across 50Hz and 60Hz electrical configurations.
- Structural Integrity Under Pressure — A correctly torqued fastener keeps pump casing joints sealed and aligned; a worn, stripped, or wrong-grade bolt risks casing separation and pump failure during operation.
- Corrosion-Resistant for Submersed Use — Specified for use in submersible pump assemblies where fasteners are exposed to continuous water contact, making material grade and surface finish critical to service life.
A socket hex bolt is a high-strength threaded fastener driven by an internal hex recess, allowing precise torque application in confined pump housing locations where a standard wrench cannot reach. In submersible pump assemblies, these bolts clamp critical casing sections together, maintaining the watertight integrity and mechanical alignment the pump depends on to move water efficiently. When a fastener corrodes, strips, or is replaced with an incorrect grade, it compromises the casing seal and internal alignment, which can lead to premature seal wear, reduced output, or complete pump failure.
