Review on 🔧 1220 PCS DYWISHKEY Hex Socket Head Cap Bolts Screws Nuts Washers Assortment Kit – M2 M3 M4 M5, 12.9 Grade Alloy Steel – Includes Hex Wrenches by Jason Hood

That's it. would buy again. I also bought some inserts for them. Depending on what I'm doing. I don't always use headphones. I just screw in my 3D prints. I'm not sure if the stakes are stronger. I haven't checked the strength but they hold up well, you can't pull them out with your fingers. I might even consider not buying any more inserts. Your printer may be different, but here's what I found on my Ender. 5.5m - 4.25mm hole 4m - 3.5mm hole 3m - 2.75mm hole 2m - I recommend using liners. The threads are very small.
