Based on common usage, 2mm and 2.5mm are very frequently used sizes for the Allen key needed for kitchen taps. However, it's important to note that these are not the only sizes you might encounter.
Understanding Tap Allen Key Sizes
When working on a kitchen tap, you might need an Allen key (also known as a hex key) for various tasks, such as:
- Tightening a loose handle.
- Removing or replacing a handle.
- Accessing cartridges for repair.
The specific size of the Allen key required depends entirely on the make and model of your tap. Different manufacturers and tap designs use different sized grub screws that require Allen keys.
Common Tap Allen Key Sizes
While tap manufacturers use a range of sizes, the reference provided highlights two sizes as particularly common for kitchen taps:
- 2mm
- 2.5mm
These sizes are prevalent, but the reference explicitly states, "we cannot guarantee that every kitchen tap out there only uses these sizes."
Why Sizes Vary
Tap Allen key sizes vary because:
- Manufacturer Design: Each company designs its taps with specific components and fixings.
- Tap Type: Different types of taps (e.g., monobloc mixers, bridge taps) may use different internal mechanisms and screw sizes.
- Age of Tap: Older taps might use different standards or less common sizes compared to newer models.
How to Find the Correct Size
Since there isn't one universal tap Allen key size, here’s how to find the one you need:
- Check the Tap Manual: The installation or maintenance manual for your specific tap model will often specify the required tool sizes.
- Try Common Sizes: Start with 2mm and 2.5mm as they are very common. See if one fits snugly into the grub screw without forcing it.
- Use a Set: Having a small set of precision Allen keys (especially in metric sizes) is the most reliable way to ensure you have the correct size on hand. Common small metric sizes include 1.5mm, 2mm, 2.5mm, 3mm, and 4mm.
| Potential Tap Allen Key Sizes |
|---|
| 1.5mm |
| 2mm (Very Common) |
| 2.5mm (Very Common) |
| 3mm |
| 4mm |
Note: Sizes can vary, this table lists common possibilities.
Ultimately, while 2mm and 2.5mm are frequently used, the exact size needed depends on your specific tap fixture.
