Heavy Duty Shield Anchor Bolts

Heavy Duty Shield Anchor Bolts are mechanical expansion anchors used to secure fixtures to concrete, brick, masonry, and other suitable solid substrates. They are commonly known as shield anchors, shield anchor bolts, fix bolts, or Rawl bolts in different markets. The anchor assembly uses an expandable metal shield together with a threaded bolt and fastening components to create a mechanical fixing point in the substrate.

This product family includes both 3-piece and 4-piece shield configurations. A 3-piece design uses three expansion segments, while a 4-piece design uses four segments around the central bolt. The segment arrangement allows the shield to expand against the walls of the drilled hole as the fastener is tightened. The specific configuration, dimensions, and expansion characteristics depend on the product design and required application.

Heavy duty shield anchors are commonly used for fixing brackets, supports, frames, machinery components, handrails, pipe supports, equipment, and other fixtures to masonry or concrete. They are particularly relevant to construction, mechanical installation, building services, and general structural and maintenance work where a mechanical expansion fixing is required.
