The Oatey HARTBBKIT Tank-to-Bowl Bolt Kit is a reliable fastening solution designed for connecting toilet tanks to toilet bowls. This kit includes brass bolts and hex nuts packaged in a clear plastic bag for easy identification and storage. Plumbers and maintenance professionals rely on tank-to-bowl bolt kits like this one to secure the connection between the toilet tank and bowl, ensuring a watertight and stable assembly. The HARTBBKIT is sized at 5/16 inches in diameter and 3 inches in length, making it compatible with standard toilet flange installations. Brass construction is a preferred material for this type of hardware because it resists corrosion from constant water exposure, outlasting zinc or steel alternatives in wet bathroom environments. When a toilet rocks, leaks at the tank, or shows signs of loose hardware, replacing the tank-to-bowl bolts is often the first step a plumber takes. This kit provides everything needed to complete that repair or new installation quickly. The 5/16 x 3 inch bolt size is a widely used standard dimension that fits most residential and light commercial toilet models. Hex nuts are included to allow for secure tightening with a standard wrench or pliers. This type of kit is a staple in any plumber's parts inventory, useful for service calls, bathroom renovations, and new toilet installations alike. The clear plastic bag packaging keeps all components together and makes it easy to verify contents before starting a job. Using quality brass hardware like the HARTBBKIT helps prevent premature corrosion, bolt seizure, and callbacks from leaking toilet connections. This is a straightforward, dependable part that meets the everyday needs of professional plumbers and contractors.
