Drop-In Anchors
An internally threaded expansion anchor with four equally-spaced slots extending from the bottom end of the outer shield, inside of which sits a pre-assembled dilating plug. Placed in a pre-drilled hole the anchor will sit flush in medium to heavy-duty applications in solid materials such as stone and concrete. When the bolt is screwed into the anchor the slots will expand and be fixed in place. It can be used in applications such as overhead assemblies such as duct work and pipe hangers because the internal plug holds its position. Can also be used to anchor handrails and floor-mounted door stops.

Double Expansion Anchors
A 4 part anchor – a two-piece tubular shield, a hollow, wedge-shaped cone and a wedge-shaped nut– brought together into one unit. The shields are connected by a pair of spring bands. At one end is the nut and at the other the cone, each designed so as to not turn during expansion. For use in soft masonry and also harder materials such as stone, brick, concrete or block. Used with machine screws or bolts which are exposed to vibration or side pressure. As the anchor sets, the opposite ends pull towards each other causing the elongation of the anchor body. It doesn’t fracture and allows for a fastening of any length.

Expansion Pin Anchors

Single Expansion Anchors
An anchor with three parts- a two-piece expansion shield held together by a steel band or wire, or interlocked by ears and lugs; and an expander nut. The outer surface of the shield is designed with ribs or corrugations to resist turning. Can be used in soft masonry and stone, brick or concrete. Used with machine screws or bolts which are exposed to vibration or side pressure. The expander nut climbs the anchor bolt as it is tightened, expanding the shield body. The bolt can be removed and replaced without affecting the holding power of the anchor system.
