Expansion

Single and Double Construction Expansion Anchors

Expansion anchors will hold securely in concrete, stone, and brick. This is thanks to an expansive action that occurs as the anchor is installed into the material, thereby tightly wedging the fastener in place.

This type of fastening hardware consists of a tubular shield and a cone nut pre-assembled into a single unit. The tubular shield and the cone nut are bound together with a spring band.

Integral lugs on the cone nut keep the wedges from turning in the tubular shield during expansion. Single expansion anchors are made from precision die-cast zinc alloy, which is non-rusting, and are commonly used for anchoring into light to medium-duty concrete, block and brick at a single point.

Double expansion anchors are made of rust-proof Zamak alloy and consist of a tubular shield, a cone nut, and a hollow cone. The tubular shield contains a wedge-shaped nut at one end and a wedge-shaped hollow cone at the other.

The expansion action at both ends distributes the anchored load throughout the length of the anchor. This type of fastening solution is designed for use where the bolt is subjected to side pressure or vibration.
