Sioux Chief Brass Closet Bolt Set with Nut & Washer

Sioux Chief Brass Closet Bolt Set with Nut & Washer

Sioux Chief brass closet bolt sets secure a toilet bowl to the closet flange during rough-in and fixture-set installation. This closet bolt family is available in 2-1/4" and 3-1/2" lengths to match different flange and toilet-base clearances, with each bolt made of solid brass for corrosion resistance in the damp floor environment around a toilet base. Every set includes a nickel-plated steel nut and a zinc-plated washer, sold two bolts per bag as a matched pair, so the connection is ready to install straight out of the bag for new construction, a remodel, or a routine fixture replacement.

Key Features

• Length Options: Available in 2-1/4" and 3-1/2" bolt lengths to fit standard closet flange slots and toilet base mounting holes across different rough-in depths.
• Brass Construction: Solid brass bolt body resists corrosion where hardware sits close to the floor drain, wax ring, and closet flange.
• Nickel-Plated Nut Included: The included nickel-plated steel nut threads onto the bolt for a secure, tight hold at the toilet base.
• Zinc-Plated Washer Included: The included zinc-plated washer distributes clamping load evenly and protects the toilet base surface at the bolt head.
• Complete Mounting Set: Packaged 2 bolts per bag, one matched pair per toilet, with the nut and washer already paired to the bolt, so a plumber does not have to source separate hardware.
• Standard Closet-Bolt Lengths: Both the 2-1/4" and 3-1/2" options give enough thread to clear the flange slot, toilet base, washer, and nut, with room to trim excess on site.

Why Sioux Chief?

Sioux Chief supplies rough-in hardware built for the realities of behind-the-wall and under-fixture plumbing work, and this closet bolt family follows that same practical approach across both the 2-1/4" and 3-1/2" lengths. Pairing a solid brass bolt with a nickel-plated steel nut and a zinc-plated washer gives a plumber a complete, corrosion-resistant mounting set in every bag instead of hunting down separate nuts and washers for each toilet. Packed two bolts to a bag as a matched pair, it is straightforward, ready-to-install hardware that keeps a service truck or rough-in kit stocked for the next toilet mount without extra trips to the supply house.
