Gunson 77080 Safety Wire Nut & Bolt Jig Kit - Metric

Bought this to aid my drilling of bolt heads and so on but not until I received it and started to use it did I realise there would be such a demand for careful technique in its use. It's not just set and drill but I got there in the end. Also it has limited use particularly when dealing with flanged bolt heads.

had to file out the inside to enable a better hole position in nuts, the original spacing was too close to the edge
