The model

Each anchor has a collar, four anti-rotation ribs, two opposite expansion slots and a tapered tip. The body is 0.5 mm narrower than the drill hole, and the ribs stand 0.15 mm proud per side and wedge the anchor in the hole.

The inner hole is meant for wood screws of 4, 5 and 6 mm (inner hole 3.0 / 3.8 / 4.5 mm). As you drive the screw in, it spreads the two halves apart.
