Sioux Chief 427-PB – Frequently Asked Questions
1) What is the difference between the Sioux Chief 425-PB and 427-PB closet bolt sets?
Bolt diameter is the difference. The 425-PB is the 5/16 inch closet bolt set and the 427-PB is the 1/4 inch set. Both are Plumb Perfect open-end nut sets with the same anti-spin base. Most toilet bowls set on 5/16 inch bolts, so match whatever diameter came out of the old flange or whatever the bowl's bolt holes will take.
2) Will the Sioux Chief Plumb Perfect closet bolts fit my existing toilet flange?
The bolt base is made to load into any closet flange, so it drops into cast iron, PVC, ABS or brass flanges with the standard slotted bolt channels. The base also holds the bolt upright and stops it spinning while you pull the nut down, which is the usual headache when resetting a bowl alone.
3) Which closet bolt length do I need, 2-1/2 inch or 3-1/4 inch?
The Plumb Perfect set comes in 2-1/2 inch and 3-1/2 inch bolt lengths. Use 2-1/2 inch on a standard flange sitting at or near finished floor height. Go to 3-1/2 inch when the flange is buried below a thick floor build-up, when you are stacking wax rings or a flange extender, or when the bowl base is tall enough that a short bolt will not leave enough thread above the nut.
4) What size socket or wrench do I need to tighten these closet bolts?
A standard 1/2 inch socket. The open end nut on the Plumb Perfect set is sized for it, so you can run the nut down with a ratchet or a cordless instead of fighting a crescent wrench in the tight space beside a bowl.
5) Will these closet bolts rust out like the old brass ones under the toilet?
The bolts are 100 percent corrosion proof, which is the point of them in a wet behind-the-wall and under-fixture location. Standard plated steel bolts seize and snap at reset time; these are built to come back apart. Each bolt is also rated above 1,100 lbs tensile, so you are not relying on a weak fastener to hold the bowl down.
6) How many closet bolts come in a box of Sioux Chief 425-PB?
Each box holds 50 pairs, so 50 toilets' worth of bolts. That is a contractor and service-truck pack rather than a single-install blister, which suits a plumbing company or an MRO stockroom turning over toilet sets regularly.
7) Can I use these for a toilet reset on an existing install, or are they only for new rough-in?
Both. The Plumb Perfect set is used for new construction toilet rough-ins and for set and reset work where you are replacing broken or corroded flange bolts. Because the base loads into any flange and keeps the bolt from spinning, it works in service situations where you cannot get a hand under the flange to hold the bolt head.
