Wacker Neuson 5000177004 PHMS Screw M4 x 6

The Wacker Neuson is a genuine OEM PHMS Screw M4 x 6 designed for the PS, PST, PSA, PSW, and PSC series submersible pumps. As a direct OEM replacement, part is sourced to match the original fastener specification used on the production line, ensuring a proper fit without guesswork. This screw is compatible across a wide range of Wacker Neuson submersible pump models, including the PS2-800, PS3-3703, PS4-3703, PS4-7503HH, PS4-7503HF, PST3-750, PSA2-800, PSA2-1503L, PSA2-2203L, PSW3-1500, PSC series three-phase pumps, and additional PS2 and PS3 variants. Keeping the correct fastener in place is a simple but essential step in maintaining the mechanical integrity of your pump assembly.

Key Features

• Genuine OEM Fastener Spec: — Manufactured to the exact M4 x 6 thread pitch and head profile specified for Wacker Neuson submersible pump assemblies, so torque and clamping values remain consistent with the original build.
• Drop-In Replacement: — Threads directly into the existing tapped bore with no rework or re-tapping required, making it a straightforward swap during routine service or rebuild work.
• Broad Model Coverage: — A single part number covers PS2, PS3, PS4, PST3, PSA2, PSW3, and PSC series submersible pumps across a wide range of voltages and motor ratings.
• Structural Integrity of the Pump Housing: — A correctly torqued fastener holds pump housing panels, motor covers, and internal brackets securely in place; a missing or stripped screw can allow vibration to shift components and compromise seal alignment.
• Verified OEM Part Number: — Cross-reference 5000177004 against your pump's parts diagram before ordering to confirm this is the correct fastener for your specific assembly point.

The PHMS Screw M4 x 6 is a pan-head machine screw used to secure housing panels, motor covers, or internal mounting brackets within Wacker Neuson submersible pump assemblies. Though small in size, this fastener plays a direct role in keeping the pump's internal and external components properly aligned and clamped under the mechanical stress of continuous submerged operation. When this screw is missing, cross-threaded, or corroded, it can allow panels to shift, compromise gasket compression, and ultimately lead to water ingress or vibration damage in surrounding components.
