MS Pin Type Anchors (Mild Steel Drive Pins / Expansion Pins) are precision-engineered fasteners designed for secure load-bearing applications in concrete, brick, and masonry substrates. Installation involves drilling a pilot hole of the recommended diameter, inserting the anchor, and applying axial impact with a hammer or mallet. As the pin expands within the drilled cavity, it forms a tight mechanical interlock, providing reliable shear and tensile load resistance.

These anchors are commonly used in structural supports, machinery base plates, safety barriers, and general construction. Made from mild steel, MS Pin Type Anchors offer strong holding power and dependable performance for indoor and dry-environment applications, though they require protective coatings or galvanization for enhanced corrosion resistance in outdoor or humid conditions.
