Fastening Systems > Concrete Double Expansion Anchor

Concrete Fastening Systems

Concrete double expansion anchors are designed for anchoring into concrete brick or block. Inserting a machine-treaded bolt expands the double expansion anchor against the concrete at two points. Double expansion allows for better holding values.

Technical Information:

The Double expansion anchor consists of a nut, a cone and a tubular shield preassembled as a single unit. The two piece tubular shield is bound together with two spring bands. It contains a wedge shaped nut at one end and a wedge shaped hollow cone at the the other end. Integral lugs on the nut and cone keep the wedges from turning in the tubular shield during expansion. The anchors are of precision die-cast zinc alloy commonly known as Zamak 5. The expansion action at both ends of the shield distributes the anchored load throughout the length of the shield. This expansion anchor is recommended for shear loads or where the bolt is subjected to side pressure or vibration. Once fastened, the object may be unbolted, removed, and/or fastened.

Double Expansion Anchor concrete anchor/fastener -Approvals:

Meets Zamak 5 Zinc Alloy: A.S.T.M. Specification 24 (AC41A) and S.A.E. 925.

Double Expansion Anchor concrete anchor/fastener -Applications:
