Gateway Brand Top Mount Toilet Seat Bolts for Toto Toilets - THU651N Alternative (2-Pack)

Introducing the GW-TOISCWv2, a high-quality Gateway Wire-branded component designed for compatibility with select toilet seats. Unlike Toto OEM parts, this is a superior alternative for the Toto THU651N top-mounted seat hardware. Catering to installations with concealed toilet seat mounting holes, it ensures a precise fit.

Crafted in China, this part boasts a robust construction made from rubber, nickel chrome, and stainless steel. Key specifications include a bolt length of 2.813in, a gasket width of 0.646in, and a washer diameter of 0.709in. The gasket's components – flange, sphere, and shaft – measure 0.829in, 0.646in, and 0.507in respectively.

To install, begin by disassembling the provided toggle bolt assemblies. Insert the rubber gaskets into your toilet seat's mounting holes, ensuring they sit flush with the fixture base. Mount the compatible toilet seat atop the bowl and align the seat hinge holes with the bolt holes of the new gasket assembly. If necessary, remove hinge covers to access the mounting points.

Secure each washer over the hinge holes, followed by threading the compression bolts into the designated washer-hinge-gasket holes. Start by hand to avoid misalignment and potential damage. Double-check the seat position and adjust as needed. Finally, tighten the bolts using a #2 Phillips-head screwdriver, exercising caution not to over-tighten with power tools, which could lead to fixture damage.

This elongated, hidden bolt design features an expanding rubber gasket, nickel washer, and stainless steel fastener. It's ideal for toilet seats without through-holes. For detailed dimensions, consult the product description.

Remember, the GW-TOISCWv2 is the Gateway Wire replacement part equivalent to the Toto THU651N top mounting hardware, providing a seamless upgrade for most Toto soft-close and other toilet seat styles.
