Rozpěrná kotva Fischer 50493

The Fischer 50493 expansion anchor is a mechanical anchoring solution intended for use in concrete and similar solid substrates. It is 75 mm long with a drill hole diameter requirement of 14 mm and a minimum embedment depth of 90 mm. Supplied in a pack of 10 in a compact box, this anchor is suitable for fixed installations where a secure, load-bearing connection to concrete is required.

Advantages

The anchor design provides reliable expansion-based fixing in concrete, delivering consistent performance when installed to the specified depth and hole diameter. Its length and expansion mechanism allow for secure load transfer into the base material while the packaged quantity of ten pieces supports small to medium sized projects. The product's dimensions and simple installation process reduce preparation time on site.

Suitable for

• Fixing structural and non-structural loads to concrete
• Mounting brackets, rails and frames
• Securing machinery bases and equipment to solid floors
• Installing heavy utilities such as pipe clamps and conduit supports

Key specifications

• Anchor length: 75 mm
• Required drill hole diameter: 14 mm
• Minimum embedment (drill hole) depth: 90 mm
• Pack quantity: 10 pieces
• Intended base material: concrete and similar solid substrates

How to use

Drill a hole in the concrete using a 14 mm masonry bit to a minimum depth of 90 mm, ensuring the hole is clean and free of dust. Insert the expansion anchor fully into the hole until the head is flush with the surface. Tighten the fixing screw or bolt to the required torque to activate the expansion mechanism and secure the anchor in the base material. Verify the installation by checking that the anchor is seated and the connected fixture is stable.

Recommendations

Use a hammer drill for accurate hole drilling in concrete, and clear the hole with a brush or compressed air before insertion. Adhere to the specified drill diameter and embedment depth to achieve rated performance. For critical or load-bearing applications, follow relevant engineering guidelines and, where necessary, consult structural documentation or a qualified engineer.
