Hayward TANK BOLT SET

The Hayward Tank Bolt Set is a specialized hardware kit engineered to provide the high-torque clamping force necessary to secure the upper and lower halves of a pressurized filter tank. Manufactured from high-tensile, 300-series stainless steel, these bolts are designed to resist the corrosive effects of salt-water systems and pool chemicals while maintaining structural integrity under significant hydraulic pressure. Their primary mechanical function is to ensure a uniform, airtight seal across the main tank gasket or diaphragm, preventing leaks and hazardous pressure loss during the filtration cycle. Each bolt in the set is typically paired with a matching nut and washer to distribute the load evenly across the tank’s reinforced flange, which protects the composite housing from localized stress fractures. These fasteners are built with precision-cut threads to prevent galling or stripping during repeated seasonal maintenance and disassembly. For shipping and logistical purposes, the estimated weight of the Hayward Tank Bolt Set is approximately 1.4 pounds in its retail protective packaging, while the actual dry weight of the hardware components themselves is roughly 1.1 pounds.
