Bison Pumps offers Stainless Steel Security Anchor Bolts for flange installations onto concrete. These bolts are installed directly into the concrete in a pattern that corresponds to the flange being installed. Set the flange in its desired location, install the anchor bolts, and fasten using the required Security Anchor Bolt Bit until tight. Be sure to tighten each bolt on opposite sides to maintain even pressure on the flange providing a solid installation.
