Removing expansion screws can be a straightforward process, especially when following specific techniques designed for the type of anchor installed.
When dealing with certain types of expansion anchors, a specific method can be employed to loosen and extract the screw and its sleeve from the wall. This method involves a sequence of steps focusing on detaching the anchor from the wall material.
Method for Removing Expansion Screws (Based on Reference)
Based on the provided reference, here is a method for removing expansion screws:
- Step 1: Remove the Cap
- Begin by removing the screw cap if one is present. This exposes the head of the screw for further manipulation.
- Step 2: Tap the Screw Inward
- Contrary to simply pulling, the next step is to tap the screw into the wall with a hammer. This action can help disengage or loosen the expansion sleeve from the wall material.
- Step 3: Extract the Iron Sheet (Sleeve)
- After tapping the screw inward, use pliers to pull out the iron sheet or expansion sleeve that is outside the screw and embedded in the wall. Focus on gripping the sleeve and carefully pulling it free.
- Step 4: Clamp the Screw
- Once the iron sheet (sleeve) has been pulled out, use pliers to clamp the screw itself.
- Step 5: Pull and Shake
- While clamping the screw with pliers, shake it while pulling to work it free from the remaining part of the anchor or the hole.
This method is particularly applicable to expansion anchors that consist of a screw and an outer sleeve that expands within the wall. By following these steps, you can effectively remove the expansion screw and its associated components.
