12mm drop in anchor

a specific size of drop-in anchor used for anchoring bolts, screws, or threaded rods into concrete or masonry surfaces. Here’s a breakdown of what each part of the term typically means:

• 12mm: This indicates the diameter of the drop-in anchor. In this case, it’s 12 millimeters in diameter. The diameter of the drop-in anchor corresponds to the size of the hole that needs to be drilled into the concrete or masonry surface for installation.
• Drop-in Anchor: This refers to the type of anchor being used. Drop-in anchors are designed to be inserted into pre-drilled holes in concrete or masonry surfaces. Once inserted, a bolt or threaded rod is tightened into the anchor, expanding its internal threaded portion and securing it tightly against the walls of the hole.
