The Wacker Neuson Screw is a genuine OEM component designed for the APT4S and APT4T pump series, including standard, cold weather, surge brake, and electric brake configurations. As a factory-sourced part, it meets the exact material and dimensional specifications set by Wacker Neuson, ensuring it seats and torques correctly without rework or modification. This screw covers the full APT4S and APT4T lineup, making it the right choice whether you're servicing a skid-mounted pump or a cold weather variant.
Key Features
- OEM Thread and Material Spec — Manufactured to the exact thread pitch, grade, and material composition specified by Wacker Neuson, so it drives and seats correctly the first time.
- Direct-Fit Replacement — Replaces the original 5200021006 Screw and installs into the same position without re-drilling, re-tapping, or adjustment.
- Broad APT4S and APT4T Coverage — Compatible with APT4S Pump with Skid, APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, and all corresponding cold weather variants.
- Structural Integrity Under Pump Vibration — A worn or incorrect screw can work loose under the sustained vibration of pump operation, leading to component shifting or damage; this OEM replacement maintains the clamp load the assembly depends on.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so the part number, specification, and fit are verified before it ships.
A screw may be a small component, but in a pump assembly it plays a critical role in holding structural and functional parts in their correct position under load and vibration. When a screw is missing, damaged, or substituted with an incorrect grade or thread size, it can cause misalignment, accelerated wear on surrounding components, or outright mechanical failure. Using the correct OEM screw ensures the fastener performs as the original design intended throughout the service life of the pump.
