Professional Notes

The Hercules Johni-Bolt design incorporates a captive washer that stabilizes the bolt vertically within the flange slot, preventing displacement during fixture alignment. The patented snap-off slot allows installers to remove excess bolt length cleanly with standard pliers after fixture placement, reducing finishing time and eliminating exposed threads. The brass construction provides durability and ensures compatibility with all flange materials without risk of corrosion or thread damage. The Johni-Bolt XL version is available for extended-length applications where multiple floor layers require greater bolt reach; these variants are smooth-shaft and can be cut flush to field requirements.
