NACX Ball Plunger, Ball Detent, Spring Plunger Screw, 20Pcs (3 x 4, 10N)

I picked up the 2x3mm one for a case project I'm working on. I'm actually surprised how well these work given the size of it. How is that even possible?! I give this 10/10.

Exactly as described.

Unfortunately the ball plungers were not the correct size. I returned them in the unopened package as I could tell that they were to small. The return process was very easy. Thank you for the rapid refund.

I use these everyday for one of my products. Never had a problem. Consistent sizes.

These work well for 3D printed parts such as slide latch lids. The prints do need to be thick enough to support these tiny parts so they don't punch through the plastic.

Under no circumstances would I ever use these things again, or anything made by this company. I measured my oiler hole with calipers. It is 6mm. They say these are 6mm. They are not. I put one in and it went right to the bottom of my lathe cross slide. I literally spent almost two days trying to get it out. I had to completely disassemble the lathe cross slide including dropping the cross slide gearbox and removing the drive rods These are a nightmare!! DO NOT USE THESE UNDER ANY CIRCUMSTANCES unless you enjoy colossally wasting your precious time. Even the flange on top which is supposed to keep them from dropping into a hole is way too small

Better than I expected.

Required a but of retrofitting but fit the need
