Nayna Enterprise Brass Expansion Anchors are fasteners intended for use in masonry bases that offer holding force through expansion. Pre-expanded and unexpanded expansion anchors are both available.

What is the difference between expansion bolt and anchor bolt?

The expansion anchor bolt will expand as it goes through the hole.The anchor bolt and the item or structural component to which it is linked are held firmly in place thanks to its expansion. Given that it is inserted in a pre-drilled hole, an expansion bolt is technically a form of post-installed anchor bolt.
