Expansion-Shield-Anchors Shops in Rhode+Island, usa - Manufacturing Companies

An expansion anchor is used in high shear-load applications. There are two types of expansion anchors: double expansion and single expansion. A double expansion anchor consists of a nut, a cone, and a tubular shield that is pre-assembled as a single unit. Double expansion anchors have expansion action at both ends of the shield and distribute the anchored load throughout the length of the shield. A single expansion anchor is used with machine screws or machine bolts in concrete, brick, or stone.
