Hayward HEX NUT W/WASHER

The Hayward Hex Nut with Washer is a specialized fastening component designed to provide a secure, vibration-resistant locking mechanism for various structural assemblies within pool filtration and pumping systems. Manufactured from high-tensile, 300-series stainless steel or corrosion-resistant alloy, this hardware is engineered to maintain its grip under constant hydraulic pressure and the mechanical stresses of motor operation. Its primary mechanical function is to thread onto a mating bolt or stud to provide a localized point of compression, while the integrated or associated flat washer serves to distribute that clamping force across a larger surface area of the equipment’s plastic or composite housing. This distribution of pressure is critical for preventing stress cracks in delicate manifolds or pump feet and ensures a uniform seal on pressurized gaskets. Designed to withstand long-term exposure to salt-chlorine environments and moisture without seizing or oxidizing, this set is essential for the long-term structural integrity of the equipment. For shipping and logistical purposes, the estimated weight of the Hayward Hex Nut with Washer is approximately 0.06 pounds in its retail protective packaging, while the actual dry weight of the individual nut and washer combination is roughly 0.03 pounds.
