Unfortunately, not all Cherry MX stems are made equal. The stem cross for each switch type vary heavily between different brands and models. You will find that the keycap will fit perfectly on some switches, and loosely on others. 
To account for this variance, the Awekeys Metal Keycap was designed with an adjustable stem to fit on most switches and stabilizers, but may require adjustments to fit perfectly.
Rest assured, this stem adjustment tool is included with the Awekeys Full Metal Keycaps Set. It’s designed to help you adjust the fit of your keycaps on various switches.
*Disclaimer Before Using the Stem Adjustment Tool:
- Always make adjustments gradually and test the keycap fit on the switch frequently until you get a perfect fit. ( The adjustment range of each pin is about 0.1-0.3mm)
- Avoid applying excessive force to prevent damage of the pin.
- Consider working on a compressible tabletop with soft surface, when hammering to prevent scratches on the keycaps.
For a Tight Fit:
Use the cross end of the tool. Gently insert it between the keycap stems to increase the gap.
For a Loose or Wobbly Fit:
Use the opposite end of the tool. Press the keycap stem into the socket to reduce the gap.
If it’s too hard to press, you can use a hammer gently as shown in the video. AVOID EXCESSIVE FORCE!
Alternative Adjustment For a Loose or Wobbly Fit:
If you prefer not to use the adjustment tool, place tape, paper, or a thin film across the stem. Aluminum foil or tape can also serve as a shim to make the stem fit more securely.
Now, place your keycap on your switch of choice all the way in and enjoy the thocky feedback a metal keycap provides!
