Hallow Bricks By TheMujtaba

• New easy fix - relief thread is easier to tighten especially at a lower torque than traditional plugged fixings
• Really easy to use. Just drill a pilot hole (see technical information below for appropriate diameter) and use a socket wrench or spanner to tighten the screw, into concrete, natural stone, solid or perforated bricks, hollow blocks etc
• Eliminates line up problems - drill the pilot hole direct into material and substrate
• No expansion force - unlike plugs or anchors - you can place nearer the edge without risk of fracturing
• Suitable for a variety of substrates - concrete, solid, perforated or hollow bricks, natural stone, marble etc
