Fischer SX Plus Expansion Anchor 8x40 mm, Nylon, 100 Pieces

The Fischer SX Plus expansion anchor is a high-quality nylon fastener engineered for reliable and secure anchoring in a wide variety of building materials, including concrete, solid brick, masonry, and gypsum fibre board. Measuring 8 mm in diameter and 40 mm in length, this anchor utilizes a 4-way expansion mechanism to ensure optimal force distribution and high load-bearing capacity. This pack contains 100 pieces, providing a professional-grade solution for both construction tasks and home renovation projects.

Advantages

The 4-way expansion design ensures superior force transmission, resulting in high holding values across both solid and perforated materials. Integrated fixing wings allow for the pre-fixation of the screw, keeping the user's hands free during installation, which is particularly beneficial for overhead work. The expansion-free neck prevents surface damage to tiles or plaster by avoiding pressure at the entry point. Furthermore, the pronounced plug edge prevents the anchor from slipping deep into the drill hole, while the distinct tightening torque provides tactile feedback to prevent overtightening.

Suitable for

• Concrete and solid masonry
• Sand-lime brick
• Gypsum fibre board
• Perforated brick
• Overhead installations

When it may not be suitable

This expansion anchor is primarily designed for solid and perforated building materials. It is not intended for use in hollow materials with large cavities where the 4-way expansion cannot achieve sufficient contact. Additionally, it should not be used in materials that cannot support the required load values or in applications requiring specialized chemical anchoring systems.

Key specifications

• Diameter: 8 mm
• Length: 40 mm
• Required drill hole diameter: 8 mm
• Material: High-quality nylon
• Expansion type: 4-way

How to use

To install the Fischer SX Plus, first drill a hole into the base material with a diameter of 8 mm. Clear the drill hole of any dust or debris. Insert the anchor into the hole until the plug edge sits flush with the surface. Insert the appropriate wood or chipboard screw through the fixture and into the anchor. As you tighten the screw, the anchor will expand in four directions to lock securely into the material. The fixing wings will hold the screw in place during the process, and the noticeable tightening torque will indicate when the installation is complete.

What to consider before purchase

• Ensure the drill bit diameter matches the 8 mm requirement.
• Verify that the base material is compatible with expansion-type anchors.
• Calculate the required screw length by adding the anchor length, the thickness of the fixture, and the screw diameter.
• Confirm the load requirements for your specific application.

Usage recommendations: For optimal performance, ensure the drill hole is cleaned of drilling dust before insertion. Use only compatible wood or chipboard screws to ensure the expansion mechanism functions correctly.
