Blue Monster’s Advantage closet bolts feature a patented broached-tip design, indicating the direction of the bolt’s foot underneath the flange while setting the toilet.  The kit contains: two solid-brass bolts, two brass open-end acorn hex nuts, two brass traditional hex nuts, two nylon Tinnerman nuts and four stainless-steel washers. The bolts feature raised knobs on the underside of the foot that prevent movement after setting the toilet. They are machined to facilitate a clean break-off at the desired level.
