Toggle bolt Fischer 44109

The Fischer 44109 toggle bolt is a fastening solution engineered for secure anchoring in concrete. At 50 mm length with a 6 mm drill hole diameter and an M6 connecting thread, this toggle bolt is intended for stable attachment of fixtures to solid base materials. Supplied in packs of 100, it is suitable for multiple or large-scale installation jobs where consistent performance and economy of components are required. The specified minimum drill hole depth of 45 mm helps ensure the toggle engages fully behind the substrate for reliable load transfer.

Advantages

The Fischer toggle bolt offers predictable load-bearing behaviour in concrete thanks to its defined geometry and M6 thread compatibility with common fixture hardware. Its 50 mm overall length and 6 mm drill diameter simplify drill selection and installation planning. Packaging in a bulk quantity reduces handling time and supports faster project workflows. The component design promotes firm expansion behind the concrete surface for secure fixation.

Suitable for

• Mounting brackets and rails to solid concrete walls
• Fixing heavier fixtures such as shelves, cabinets or lighting to concrete
• Multiple or repetitive installations on construction sites or renovation projects

How to use

Drill a 6 mm diameter hole to at least the specified minimum depth of 45 mm into the concrete surface using appropriate masonry drill bits. Clean the hole of dust and debris before inserting the folded toggle component into the hole until it opens fully behind the substrate. Align the fixture over the protruding thread, then engage the M6 screw or bolt and tighten to secure the fixture. Tighten until the fixture is held firmly; avoid over-torquing which can damage the base material or the fastener.

Recommendations

Confirm that the base material is solid concrete and free of cavities or crumbling areas. Select drill bits and torque settings appropriate for M6 fastenings and the fixture weight. For safety-critical or high-load applications, verify load values and consider structural advice to ensure the chosen fastening method meets required performance criteria.
