This yellow ultra long expansion plug is a corrosion-resistant anchor designed for fixing screws into a wide range of solid and hollow substrates. Its distinctive pentagon-shaped outer ribs bite firmly into the drilled hole, preventing the plug from spinning while the screw is driven in - a common failure point with cheaper round-barrel plugs. The internal plum-blossom (flower-shaped) bore grips the screw thread securely for a strong, lasting hold.

Made from durable, non-rusting plastic, this plug resists corrosion and ageing and maintains good performance across a wide temperature range (as specified by the manufacturer, -40°C to +80°C). It is suitable for fixing electronic appliances, electrical/mechanical hardware, mobile communication equipment, power switches, light fixtures, picture frames, curtain tracks, towel racks, mailboxes, brackets, support panels, bathroom fittings and light cabinets.

Compatible substrates include solid brick, concrete, natural dense stone, hollow sand brick, solid stone slabs, porous brick, hard solid materials, wood, lightweight hollow concrete block, prestressed concrete and aerated concrete blocks.
