Hayward | SPX1600Z4 | Housing Cap Screw | Replacement Pump Fastener
The Hayward SPX1600Z4 Housing Cap Screw is a replacement fastener designed for compatible Hayward pool pump assemblies. This cap screw secures the pump housing and associated components, helping maintain internal alignment, proper sealing surfaces, and structural integrity during normal operation and routine maintenance.
Key Features
• Replacement cap screw engineered for use with compatible Hayward pool pump models.
• Secures the pump housing to support proper structural alignment and component fitment.
• Helps maintain sealing interface compression to prevent water leakage and pressure loss.
• Ideal for replacing stripped, corroded, or missing screws during pump service or rebuilds.
• Designed to withstand continuous exposure to pool water and typical operating environments.
• Direct fit fastener intended for use in routine maintenance and repair applications.
Product Overview
The Hayward SPX1600Z4 Housing Cap Screw is an essential structural fastener used to secure the pump housing and retain internal component alignment in select Hayward pool pump assemblies. Properly installed cap screws help maintain housing integrity and preserve sealing surfaces that prevent water leaks and air intrusion, both of which are vital for dependable pump performance. Over time, repeated disassembly, vibration, or corrosion can cause original screws to strip, seize, or deteriorate, compromising the housing joint and internal sealing.
Replacing worn or damaged housing cap screws with the SPX1600Z4 helps restore secure assembly integrity and maintains proper alignment of internal components. This replacement fastener is commonly used during pump maintenance, housing servicing, or complete rebuilds to support consistent circulation performance and long term reliability of compatible Hayward pool pump systems.
