The SIOUX CHIEF sc-410-pb is a 2.5-inch closet bolt sold in a 2-piece bag, designed to secure a toilet base to the closet flange during rough-in and installation. Closet bolts, also called johnny bolts, thread through the flange slots and accept a nut and washer to draw the toilet horn down onto the wax seal. This hardware is a standard consumable in residential and light commercial plumbing work, replaced whenever a toilet is reset, a flange is repaired, or existing bolts are corroded or damaged.
This closet bolt is suited for standard residential toilet installations where the rough-in flange sits at or near finish floor level. Plumbers and plumbing contractors use these bolts during new construction toilet sets and service calls involving toilet removal and reset. The 2-per-bag count matches the two-bolt requirement of a standard floor-mount toilet.
Designed as an OEM-style replacement closet bolt for standard floor-mounted toilet installations using a conventional closet flange.
Closet bolts are installed by licensed plumbers or qualified plumbing technicians. Shut off the water supply and remove all water from the tank and bowl before removing an existing toilet. Slide the bolt heads into the flange slots before setting the wax ring and lowering the toilet, as bolts cannot be inserted after the toilet is seated. Hand-tighten nuts evenly and avoid over-tightening, which can crack the toilet base porcelain.
