Hmoždinka Fischer 46703

The Fischer 46703 wall plug is a screw anchor designed for secure fastening in masonry and concrete. Intended for use where reliable load transfer and vibration resistance are required, this pack contains 20 pieces and is suitable for a variety of indoor and outdoor applications. The anchor requires a drill hole diameter of 2 cm and a minimum drill hole depth of 14 cm to achieve the specified embedment and holding performance.

Advantages

Fischer’s screw anchor offers consistent expansion behaviour in brick and concrete to provide stable anchoring. The design supports high pull-out and shear resistance when installed to the recommended depth and diameter. Supplied in a pack of 20 pieces, it simplifies ordering and stock management for small to medium projects. Certification to relevant ETA assessments confirms that the anchor meets established performance criteria for structural and non-structural fixings.

Suitable for

• Anchoring fixtures to solid brick and concrete walls
• Mounting shelves, brackets, and light structural elements
• Indoor and sheltered outdoor installations where compatible base material is present
• General maintenance, repair, and renovation projects requiring reliable screw anchors

Key specifications

• Material compatibility: brick and concrete
• Drill hole diameter: 20 mm
• Minimum drill hole depth: 140 mm
• Pack quantity: 20 pieces
• Certifications: ETA-based performance assessment

How to use

Select an appropriate fastener length so that the screw fully engages the anchor when the plug is set at the required depth. Drill a clean hole with a 20 mm drill bit to at least 140 mm depth in the base material. Remove dust from the hole before inserting the wall plug. Insert the anchor until its head is flush with the surface, then tighten the screw to expand the anchor body and achieve the designed holding action. Follow torque recommendations from the screw manufacturer and verify the installed condition visually and by testing the fixture load where safety is critical.

Recommendations

Use in solid masonry or concrete only; avoid hollow or perforated blocks unless a different anchor type is specified for those substrates. Ensure drilling is perpendicular to the surface and that hole depth and diameter match the anchor’s requirements. When installing multiple anchors for load-bearing applications, maintain the recommended spacing and edge distances specified for the base material to prevent cracking or reduced capacity.
