Wedge Anchors are an anchor that can provide a permanently threaded socket in concrete. Once installed use a proper manual setting tool or a metal rod to set the wedge. The wedge anchor allows Bolts or Studs to be installed and removed without causing damage to the anchor itself. The Wedge Anchor is also often referred to as a "Drop In Anchor". The internally threaded size of the fixing is the stated size of the anchor. The external diameter of the anchor will need a different drill size and can vary slightly manufacturer to manufacturer, we have shown the anchor hole size as a guide but you are advised to check this before drilling your hole.
