2.2 The minimum distance between a counterbore to an edge should be four times the thickness of the metal sheet. 2.3 The minimum distance between a counterbore to a bend should four times the thickness of the metal sheet + bend radius. 3. Countersinks: These are conical-shaped holes created in a metal sheet to hold a countersunk bolt or screw . Information on the necessary edge distances in wooden components can be found, for example, in DIN EN 1995-1-1: 2010-12 (Eurocode 5). There are various parameters to consider, which have an influence on the required edge distance: Direction of the grain of the wood; Angle between force and grain direction; Loaded / unloaded edgeWha are the rules for minimum and maximum edge distance? . 3xs diameter.
