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

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

Required a but of retrofitting but fit the need

Way smaller than I thought they were but they work as intended

Better than I expected.

Fit good, works good

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

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.

they work fine and plunger is not sticking
