Threads are very smooth, no issues grabbing with an M2 bolt. Would recommend, arrived in a week.

I use a bunch of these brass inserts on a couple of motorists that I manufacture, and was looking for a higher volume supplier. Have already used a portion of this order, results are good, inserts are within tolerance and threaded to M3. Recommended to anyone looking for inserts!
