Timothy ★★★★★

The spring fits perfectly on my SIEG SX2.7L, and the spindle lock now engages smoothly without any binding. It’s a small part but made a big difference in how easily I can change tooling.

Julian J. ★★★★★

Exactly the right size to replace the worn one on my SX3.5, and the engagement is nice and solid now. My only worry was getting the diameter correct, but 9mm fit perfectly.

Sophia ★★★★★

Finally got around to installing this spring and the spindle lock knob now snaps back into place perfectly — such a smooth feel compared to the old one. It's the exact 9 mm x 15 mm size needed for my mill.
