翼形螺絲，防屑護罩

The thumb screw threads smoothly into place without any tools, making it easy to swap the chip guard between machines. It’s a small upgrade that feels much more secure than the original fastener.

Had to swap out the original guard screw on my table saw and this thumb screw made the job a total breeze, no tools needed at all. The M6 x 12 thread lined up perfectly and it tightens down securely by hand in seconds.

The M6 threading matched my bench machine perfectly, so the chip guard now clicks into place without needing a wrench. It's a small fix, but the tool-free swap is exactly what I needed for quick adjustments between cuts.
