Bsc Preferred DIB835-18 Tank Bowl Bolt Set 5/16x3 Brass

Product Description

The BSC PREFERRED DIB835-18 is a close-coupled tank and bowl bolt kit designed for standard two-piece toilet installations. Each set includes 5/16-inch x 3-inch brass-plated slotted head bolts, metal washers, rubber washers, and wing nuts — all the hardware needed for a complete tank-to-bowl connection. The brass-plated finish provides corrosion resistance in wet environments. This hardware is a staple for plumbers performing toilet installations, replacements, or tank reseats in residential and light commercial settings.

This bolt kit is suited for close-coupled two-piece toilet assemblies where the tank mounts directly to the bowl. It is commonly used in residential bathrooms and light commercial restrooms. The included rubber washers create a watertight seal between the tank and bowl, while the metal washers and wing nuts secure the assembly. Plumbers and fixture installers will find this kit appropriate for new installs and service calls involving leaking or damaged tank hardware.

Installation Notes

Installation is typically performed by a licensed plumber or experienced fixture installer. Shut off the water supply and flush the tank to empty it before removing or installing tank bolts. Tighten wing nuts evenly and incrementally, alternating sides, to avoid cracking the tank or bowl — do not overtighten. Follow applicable IPC or local plumbing code requirements for toilet fixture installation.
