Internal Threaded Anchors

Our collection of heavy-duty internal threaded anchors provides a versatile and flush-fitting solution for permanent fixings in solid concrete and masonry. Primarily featuring "Drop-in Anchors," these fixings allow for the easy insertion and removal of bolts or threaded rods, making them ideal for overhead pipework, ducting, and suspended ceilings. Once set with a manual punch, the internal thread remains fixed in the substrate, offering high-strength support without any protruding studs.

Available in high-quality Zinc Plated and Stainless Steel finishes, these anchors ensure long-lasting durability for structural and mechanical installations. For projects requiring a clean look, we recommend our Lipped Drop-in Anchors, which prevent the anchor from disappearing too deep into the drill hole. For standard heavy-duty applications, our Zinc Plated Drop In Wedge Anchor is a popular, reliable choice.
