17mm hex socket tolerances needed

[maximum15]

Can someone tell me where to locate standard manufacturing tolerances for a 17mm, six-point, hex socket? I need tolerance on socket flat to flat dimension as well as lead-in chamfer or radius size.

Have you considered adopting the dimensions and tolerances for British Standard socket set screws? The Machinery's Handbook give tables of dimensions and tolerances and the lead in chamfer diameter is generally the width across corners dimension. Tommy
