  • Good high quality
Item Package Quantity: 300 Size: M4 x D6 x L6
This was my first use of heat inserts. Not only were these easy to install, but the screws had no issues going into them. If I need more I will be buying these again.

  • Never going back
Item Package Quantity: 500 Size: M3 x D5 x L4
These are specifically designed for 3d printing it makes using inserts much easier 4.2 mm hole and it will fit snug to press in. These get larger as they go up so your going to get a grip into the plastic. Way better than using regular brass inserts.
