Carter N. ★★★★★

The 3mm diameter is spot-on for jig alignment, and the 18mm length gives just enough bite for my drill press table setup. They seat firmly without any wobble, which is exactly what you want from a parallel pin.

Carter ★★★★★

Picked up a set of these M3x18 pins for a quick alignment fix on my drill press jig, and the 3mm diameter fit perfectly into the pre-drilled holes. The parallel sides kept everything snug without binding, which made the setup a lot smoother.

Natalie ★★★★★

I needed an exact 3mm pin to align two jig plates, and the 18mm length fits perfectly without any extra trimming. The machining on this little dowel is clean and burr-free, which made installation a breeze.
