Name: Petal Nut/Jack Nut
Material: carbon steel
Process: Galvanized
Size: M5x25

Feature:
Will not twist or deform soft plastic or thin metal sheets with peeled holes. Use these nuts and they work great. With brackets installed, the upper part of the door is also stronger.

Parts are made of high-strength steel. Zinc finish for improved corrosion resistance. High hardness high quality carbon steel. Galvanized surface, anti-corrosion and anti-oxidation, no burr, flanging anti-skid design, wear-resistant, very practical.

How to use: First align the diameter, tap the anchor into the hole until it is flush with the surface of the substrate, then attach the installation tool to the screw head. Squeeze to expand the anchor. (Small sizes can be set with a screwdriver) Finally remove the screw and put it back in the anchor through the fixture. Tighten the screws until the fixture is secure.

Warm Tip: Just choose the right tip, don't install the rail, so you can get closer to the jack nut flange. Again, these are light to use and don't require putting something heavy.
