Hi everyone, my job this weekend is to fit a 16kg 9" woodwork vice under my workbench and I'm in two minds of the best way to fasten it. I'm leaning toward 75mm coach bolts screwed into the underside of the bench but I'm also playing around with the idea of using nut & bolts passing right through the bench.
Obviously the coach bolts won't penetrate the surface, whereas if I go for nut&bolt the head of the bolt will need to be countersunk into the top of the workbench.
The total width from lower side of the vice to the top of the bench is 90mm, made up as follows:
I'm thinking four 75mm long coach bolts will give me 30mm screw penetration into the benchtop, which should hold the vice well enough. On the other hand, running four 90mm nuts&bolts through the benchtop will guarantee the vice never moves, but I'll have four countersunk bolt heads spoiling my workbench.
Any thoughts?

The total width from lower side of the vice to the top of the bench is 90mm, made up as follows:
- The bench top is 45mm thick hardwood.
- A ~25mm hardwood spacer between the vice and the bench.
- The vice has four mounting holes about 20mm deep and 12mm wide.
