The M16 Heavy Duty Shield Anchor (Rawlbolt) is a high-grade mechanical expansion anchor designed specifically for high-load fixings into solid concrete, masonry, and stone. Unlike standard hex bolts that require a nut on the opposite side, this expansion anchor creates its own powerful friction hold inside a drilled hole, making it ideal for blind-hole mounting applications.
Key Technical Details
-
Heavy-Load Capacity: Engineered to sustain immense shear and pull-out forces, making it perfect for supporting heavy wall-mounted structures such as battery shelves, inverter racks, and heavy steel brackets.
-
4-Segment Expansion Sleeve: As the bolt head is tightened, the internal wedge expands four robust steel segments uniformly against the walls of the masonry, providing continuous grip without slipping.
-
Corrosion Resistance: Coated with bright zinc plating or yellow passivation to guard against indoor humidity, mechanical wear, and atmospheric oxidation.
-
Simple & Secure Mounting: Installed directly through the fixture into a pre-drilled concrete hole without needing rear access to secure a nut.
Primary Applications
Widely used for securing heavy-duty steel wall brackets (such as those holding solar inverters, batteries, or transformers), structural steel posts, heavy machinery bases, and safety barriers onto concrete walls and floors.
