MECHANICAL ANCHORS

Mechanical Anchors

Mechanical anchors rely on friction, expansion, or physical keying into solid materials like cured concrete or dense stone.

  • Through Bolts (Wedge Anchors): A threaded bolt featuring a small expansion clip at the bottom. As the nut is torqued, the clip expands against the walls of the drilled hole. They are ideal for structural steelwork, bracketry, and timber-to-concrete fixtures.
  • Shield Anchors: Often known as a RAWLBOLT, this is a multi-piece expansion fixing featuring a split shield that opens outwards along its entire length when a bolt or hook is tightened inside it. These are highly effective in older concrete or solid brickwork where hole quality is imperfect.
  • Sleeve Anchors: A versatile, pre-assembled fixing consisting of a threaded bolt surrounded by a full-length metal sleeve. Tightening the bolt pulls a tapered cone into the sleeve, forcing it outwards. They are excellent for concrete, brick, and hollow block structural connections.
  • Concrete Screws (Self-Tapping Anchors): High-strength steel screws that cut their own thread directly into a pre-drilled concrete hole. Because they do not exert expansion stresses on the concrete, they can be used closer to edges without splitting the substrate.
  • Drop-in anchors are heavy-duty, deformation-controlled expansion fasteners designed exclusively for permanent use in solid concrete and stone. They feature an internally threaded female socket, allowing a bolt or threaded rod to be inserted, removed, and replaced repeatedly without compromising the anchor's hold. Because they sit flush with the surface, they are widely preferred for overhead ceiling installations, strut frameworks, and pipe suspensions.
