Pentair .25-20 x 1.25" Stainless Steel Screw

The Pentair 0.25-20 x 1.25" Stainless Steel Screw (Product #: 98212100) is a factory-original OEM replacement fastening hardware component designed to provide heavy-duty structural anchoring across a variety of premium pool and spa equipment pads. Commonly utilized to secure high-stress assemblies such as chemical feeder lids, pump pot strainers, and various valve cover plates, this industrial-grade screw ensures that pressurized components stay safely sealed against extreme internal forces. Precision-machined from a high-tensile, marine-grade stainless steel alloy, this fastener delivers total immunity to galvanic corrosion, heavy rust oxidation, and aggressive pool sanitation chemicals like concentrated chlorine, bromine, and high salt levels. The precision-cut external threads feature a standard 1/4-inch diameter with a coarse 20 threads-per-inch (TPI) pitch and a 1.25-inch shank length, engineered to mate flawlessly with factory threaded inserts to absorb the continuous hydraulic line surges and motor vibrations generated by high-performance circulation pumps operating at pressures up to 50 PSI. The physical dry weight of this single, ultra-robust Pentair Stainless Steel Screw is approximately 0.022 pounds (roughly 0.35 ounces, with a nominal packaged shipping weight of 0.05 pounds), providing pool service technicians and residential operators with an indispensable, highly durable, and corrosion-proof hardware standard for safe pool water management.
