FISCHER wall plug UX 12 x 70, universal screw anchor for brick and concrete, pack of 2

FISCHER wall plug UX 12 x 70 is a universal screw anchor designed for secure fixings in solid masonry such as brick and concrete. Supplied as a pack of 2, these 70 mm long anchors require a 12 mm drill hole and a minimum drill depth of 100 mm. The UX design adapts to different base materials by splitting and gripping the substrate as the screw is tightened, providing strong load-bearing performance for a range of interior and exterior mounting tasks.

Advantages

The universal geometry of the UX wall plug ensures reliable expansion and load transfer in solid masonry and concrete. Its 70 mm length and 12 mm diameter allow deep anchoring for higher pull-out and shear values compared with shorter plugs. Supplied in a compact pack of two, these anchors are suitable for individual fixtures where durable fastening is required. The product's straightforward installation procedure reduces installation errors when used with the recommended drill size and depth.

Suitable for

• Mounting shelves, brackets and cabinets to brick or concrete walls
• Securing handrails, supports and heavy fixtures in masonry
• Anchoring external fittings that require strong load-bearing points in solid substrates

When it may not be suitable

These UX 12 x 70 universal plugs are intended for solid base materials such as brick and concrete. They are not intended for use in hollow or cavity blocks, lightweight aerated concrete without appropriate preparation, or thin panels where the required drill depth and substrate thickness cannot be achieved. For installations in soft or hollow substrates, different anchors or additional measures (such as chemical anchors or cavity-specific fittings) should be considered.

Key specifications

• Anchor type: universal screw anchor for solid masonry
• Anchor length: 70 mm
• Required drill hole diameter: 12 mm
• Minimum drill hole depth: 100 mm
• Pack quantity: 2 pieces
• Suitable base materials: brick, concrete

How to use

Drill a hole of 12 mm diameter to a minimum depth of 100 mm in the chosen brick or concrete substrate. Clean the drilled hole of dust and debris with a brush or compressed air. Insert the UX 12 x 70 wall plug flush with the surface. Position the fixture and drive the appropriate screw into the plug until the anchor expands and grips the substrate; tighten to the required torque for the specific screw and load. Follow standard safety practices and use a drill with the correct masonry bit.

What to consider before purchase

• Verify the substrate is solid masonry or concrete and has sufficient thickness for a 70 mm anchor and 100 mm drill depth
• Confirm the drill bit diameter of 12 mm and suitable screw diameter for the intended load
• Assess whether two anchors are sufficient for the fixture or if additional anchors are required

Usage recommendations

Use the UX 12 x 70 with the correct masonry drill bit and clean the hole thoroughly before insertion. For heavy or safety-critical fixings, consult load tables or manufacturer guidance to select the correct screw size and number of anchors. Avoid using these anchors in hollow materials without appropriate alternative fasteners.
