sheet metal hole distance from edge 3. The minimum distance between the hole or slot and the edge of the sheet should be three times of sheet thickness. Min. Edge-to-hole distance= 3 x thickness. 4. If the custom sheet metal fabrication design has semi-pierced . Octagon (ceiling) box screws are 8-32. Wall box screws are 6-32. Fan support box screws and ground connection screws are 10-32. Both ceiling and wall box screws are typically about 1-1/4" long, combo head.The most common size screw to use in an electric box is a 6-32 flathead screw. For heavier applications, like ceiling lighting and ceiling fans, an 8-32 screw will work better. Ground screws in electrical boxes are always 10-32 .
