Description: |
| Abstract from ESPACENET: "Bolts for a belt fastener have spikes G on their heads, which are forced into the belt and prevent the bolts from rotating while being tightened up. The nuts D are extended at H to increase the depth of the screwed portion, and the holes J, by which the nuts are turned, are elongated in a radial direction so that a single key or spanner may fit nuts of different sizes."
