Hercules Johni-Bolts are solid brass closet bolts engineered to securely fasten water closets to flanges during new installations or replacement projects. The captive washer design keeps the bolt upright and prevents it from falling through the flange, eliminating a common installation frustration.
The patented snap-off slot design allows you to trim bolts to the exact length needed without requiring additional tools, making installation faster and more convenient. Paired with oversized solid brass acorn nuts and stainless steel washers, this system delivers both strength and ease of use. The complete package prevents bolts from loosening over time, ensuring your water closet remains securely fastened.
