Oatey PP835-17 Toilet Closet Bolts 5/16-20 X 2.25 in

Product Description

The OATEY PP835-17 is a pair of toilet closet bolts sized 5/16-20 thread by 2.25 inches in length, used to anchor a toilet bowl to the floor flange. These bolts slide into the slots of a standard closet flange and secure the toilet base, distributing clamping load evenly when the nuts and washers are tightened. Plumbers and experienced DIYers install these during toilet replacement or flange repair work. The threaded shank engages a standard 5/16-20 nut configuration, and the bolt head is designed to seat flush inside the flange channel without rotation during installation.

These closet bolts are suited for residential toilet installations where the existing hardware is corroded, broken, or missing. They are a direct service replacement installed during toilet removal and resetting, typically as part of wax ring replacement, flange repair, or full toilet swap-out. The card packaging contains the hardware needed to complete a standard two-bolt toilet mount.

Key Features

• 5/16-20 thread specification for standard closet flange nut compatibility
• 2.25-inch length accommodates typical flange height and wax ring stack
• Designed to seat and lock within standard closet flange slots without spinning
• Card packaging keeps hardware organized for single-job use

Compatibility

Designed as an OEM-style replacement for standard residential toilet closet flange bolt applications.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply and drain the toilet tank and bowl before removal. Slide the bolt heads into the flange slots before setting the toilet, and do not overtighten the nuts, as excess torque can crack the toilet base porcelain. Follow local plumbing code requirements, which may reference IPC standards for fixture connections.
