Hotbed clip and washer

Hotbed clips and washer for p3 steel. The glass is 4mm. screw: M3x25 spring diameter: 6 mm.
This hotbed clip, the screw and the spring has two functions:
1. It allows easy bed leveling.
2. Holds the glass in place.
The washers avoid the tearing of the electrical circuit under the hotbed. I strongly recommend the use of the washers.
