Explanation of the table: SD = screw diameter; ND = boss internal diameter; KD = screw head diameter. All dimensions in mm.
In most BOPLA plastic enclosures, mounting bosses without threaded bushings are provided as mounting points. Screws with a self-tapping thread must be selected accordingly. When selecting screws, note the details of the boss internal diameters (see drawings on internet) and the drilling depth. The tightening torques for plastic depend on screw-in depth, screw-in speed, accuracy of torque switch-off of the power screwdriver, etc., so it is not possible to provide general data about the tightening torques.
