Expansion anchor FISCHER KD 4 B, 105 mm length, pack of 10

FISCHER KD 4 B expansion anchor, 105 mm length, pack of 10 is a mechanical anchor designed for secure fixing in solid base materials such as concrete and masonry. The anchor transfers load through controlled expansion, providing a stable connection for medium-duty fastening tasks. Supplied in a ready-to-install pack of ten, it is intended for use where repeatable, reliable performance is needed on construction sites and renovation projects.

Advantages

The design of this expansion anchor ensures uniform expansion in drilled holes, which improves load distribution and reduces the risk of pull-out in solid substrates. With a length of 105 mm, it reaches sufficient embedment depth for common medium-duty applications while remaining compact for easier handling and installation. The anchors are delivered as a set of ten, allowing multiple fixings to be completed without repeated packaging opening. The mechanical expansion principle avoids chemical adhesives and enables immediate loading after installation, accelerating workflow on site.

Suitable for

• Mounting brackets and fixtures on concrete walls and floors
• Fixing rails, channels and light structural elements in masonry
• Securing machinery guards, cable trays and small supports
• Renovation and repair tasks requiring medium-duty anchors

Key specifications

• Anchor type: mechanical expansion anchor
• Length: 105 mm
• Pack quantity: 10 pieces
• Suitable base materials: solid concrete and masonry
• Load transfer: expansion-based

How to use

Drill a hole in the base material to the required diameter and depth according to the anchor size. Clean the hole thoroughly from dust and debris using a brush and blowing or vacuuming. Insert the anchor into the hole until the collar rests on the surface. Tighten the nut or bolt to the specified torque so the sleeve expands and engages the substrate. Verify the seating and clearance, and subject the anchor to the intended load only after correct installation is confirmed.

Usage recommendations

Use in solid substrates only; do not use this expansion anchor in hollow or perforated blocks without additional measures. Follow drilling diameter and embedment depth guidance for the specific base material. For safety-critical or high-load applications, consult design tables or a structural engineer to confirm suitability and spacing requirements.
