INDEX® drop-in expansion anchors 08 October 2021

The INDEX® range of drop-in expansion anchors with internal thread are designed for installing pipework, cable trays, ventilation ducts or fire sprinkler systems and are available with ATLANTIS C3-L, A4 stainless steel or zinc plated coating for use in both indoor and outdoor applications.

Available in seven different models for greater versatility, to cater for the needs and requirements of each application, this range is approved according to the highest quality standards –  (ETA – 14/0135) for redundant non-structural systems in cracked and non-cracked concrete (C12/15 to C50/60), including under conditions of fire exposure; (ETA – 14/0068) for structural applications in non-cracked concrete (C20/25 – C50/60); as well as FM approval for use in fire sprinkler systems.

Available in a wide range of metrics sizes M6 – M20, the drop-in expansion anchors also feature maximum versatility with the metric inner thread allowing them to be used in multiple installations with metric bolts and/or threaded bars.

Also available is a new short version, which allows easy installation in base materials of low thickness, as well as an EXP tool with rubber protection to enable safe, controlled and ergonomic expansion of the anchor. The anchors are also removable and reusable due to the removal of the bolt or bar, which leaves a clear surface.

“Our manufacturing allows us to ensure a rigorous control of processes; guarantee the highest quality in our products; as well as provide the best service and obtain a competitive global cost,” comments INDEX® – A Perfect Fixing.
