Galvanised sleeve anchors, commonly referred to as a dynabolts are an economical torque setting expansion anchor designed for medium duty fixing to concrete and solid masonry. Sleeve anchors are to be inserted into a hole drilled the same diameter as the anchor. Once the anchor has reached the desired embedment depth the nut is to be tightened, this forces the sleeve to expand over the base of the anchor and into the sidewall of the hole, creating a reliable fixing connection. Sleeve anchors are commonly used for anchoring handrails, guardrails, steel brackets and bottom plates.
