Introduction
The fischer expansion plug S is a classic and widely proven fixing solution, manufactured from high-quality nylon. This robust design ensures secure installation and long-lasting reliability. Its unique two-directional expansion mechanism allows for precise force distribution, preventing damage to the building material, especially near edges. It is compatible with wood or chipboard screws and is ideally suited for applications in concrete and solid masonry.

Key Features
- Anti-Rotation Lock: Prevents the plug from rotating within the drill hole, ensuring a high degree of installation safety.
- Two-Directional Expansion: Directs expansion forces parallel to the edge of the building material, minimizing the risk of spalling.
- Versatile Installation: Suitable for both pre-positioned and push-through installation methods.
- High-Quality Material: Made entirely from durable nylon for robust and permanent security.
- Easy Insertion: Designed for simple and effortless pushing into the drill hole.
Installation Guide
1. Preparation
- Select the Correct Drill Bit: For the fischer S12 plug, use a drill bit with a diameter of 12mm (approximately 1/2 inch).
- Determine Drill Depth: The drill depth should be at least 90mm to ensure full engagement of the plug.
- Clear the Drill Hole: After drilling, remove any dust or debris from the hole to ensure optimal grip.
2. Installation Steps
- Insert the Plug: Push the fischer S12 expansion plug into the prepared drill hole until it is flush with the surface of the building material. The rimless design allows for both pre-positioned and push-through installation.
- Insert the Screw: Use a wood or chipboard screw with a diameter between 10-12mm. Drive the screw into the plug. As the screw enters, the plug will expand in two directions, creating a secure anchor.

Note: The anti-rotation lock on the plug prevents it from spinning during screw insertion, ensuring a stable and reliable connection.
Operating Principle
The fischer S12 expansion plug operates on a simple yet effective principle. As a screw is driven into the plug, the plug's body expands outwards in two opposing directions. This expansion creates a strong frictional fit against the walls of the drill hole, providing a secure anchor point. The high-quality nylon material ensures durability and consistent expansion performance across various solid building materials.
Maintenance
The fischer S12 expansion plug is designed for permanent installation and requires no ongoing maintenance after proper installation. Ensure that the plug is not exposed to extreme temperatures or corrosive chemicals that could degrade the nylon material. If a plug needs to be removed, it typically involves extracting the screw and then carefully prying out the plug, which may damage the plug itself, requiring replacement for re-use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Plug spins in hole during screw insertion. | Drill hole is too large, or debris in hole. | Ensure correct drill bit size (12mm). Clean drill hole thoroughly before insertion. |
| Screw does not fully engage or feels loose. | Incorrect screw diameter or insufficient drill depth. | Use a screw with 10-12mm diameter. Ensure drill depth is at least 90mm. |
| Material spalls or cracks near the edge. | Plug inserted too close to the edge without proper orientation. | Ensure the plug's expansion direction is parallel to the edge by turning the plug before inserting the screw. Maintain adequate distance from edges. |
