Hayward FILTER HEAD SCREW SET

The Hayward Filter Head Screw Set is a specialized hardware kit designed to provide the necessary clamping force to secure the filter head or cover to the main tank body on specific pool filter models. Typically manufactured from high-grade, corrosion-resistant stainless steel or zinc-plated alloy, these screws are engineered to withstand the significant hydraulic pressure generated within the filter vessel without stretching or shearing. Their primary mechanical function is to ensure a uniform, airtight seal across the main tank gasket, preventing leaks and maintaining the system's internal pressure for efficient water clarification. These screws feature high-strength threading and heads designed for a secure fit with standard tools, allowing for repetitive removal and re-tightening during seasonal maintenance or cartridge cleanings. Because they are exposed to the elements and pool chemicals, the material is specifically chosen to resist oxidation and salt-air degradation. For shipping and logistical purposes, the estimated weight of the Hayward Filter Head Screw Set is approximately 0.45 pounds in its retail protective packaging, while the actual dry weight of the individual screws and any included washers is roughly 0.32 pounds.
