Original Press Release:

CONFAST® New Mushroom Head Anchor

“The CONFAST® Mushroom Head Anchor, a one-piece pre-expanded anchor for use in concrete, brick, block or stone, has now joined our online product inventory,” stated Bob Carlisle, the founder and president of Concrete Fasteners, Incorporated. “Customers may purchase this popular expansion anchor direct from the manufacturer and avoid inflated retail pricing.”

Carlisle described the one piece, pre-expansion design of the CONFAST® Mushroom Head Anchor as unique. The working end of the anchor is “s-shaped”. This pre-expanded feature, when driven into the base material, will attempt to return to its original shape and thereby creates a natural compression force against the wall of the hole drilled in the base material.
