Supplied in a pack of four with a silver finish, these anchors combine a compact design and robust holding performance for a range of building and repair tasks. The product suits users who need reliable fastenings for fixtures where a strong, vibration-resistant connection is required.

Advantages

The anchors offer consistent expansion behavior to produce a secure grip in drilled holes in brick and concrete. Their metal construction provides durability and resistance to mechanical stress. The silver finish reduces corrosion exposure in typical indoor and sheltered outdoor conditions. The compact pack of four makes it convenient to carry a small quantity for on-site adjustments and minor installation jobs.

Key specifications

• Material: metal anchor body suitable for solid masonry
• Finish: silver
• Intended base materials: brick and concrete

How to use

Drill a hole in the masonry to the specified diameter and depth for the anchor size. Clean the hole from dust and debris to ensure full contact between the anchor and the substrate. Insert the anchor and drive a compatible screw to activate the expansion mechanism; tighten to the required torque without over-torquing. Follow standard safety procedures and use correct drill bits and screw types for best results.

Recommendations

Check the load requirements of the fixture and the properties of the masonry before installation. For critical or heavy-duty applications, refer to structural guidelines or consult a qualified installer. Avoid use in hollow or weak substrates; select an anchor type appropriate for those conditions. Store anchors in a dry place to reduce corrosion risk.
