Nettet12. nov. 2024 · Use a bolt diameter that is 1.5 – 2.5 times (up to three times) the thickness of the thinner material you are bolting together. So, for 1/8″ material, a 1/4″ diameter is often a good bolt choice. For 1/4″ thick material, perhaps a 3/8″ or 1/2″ bolt. This guideline falls apart for very thin materials, and for really thick stuff. NettetNormally, when calculating the PCB hole diameter, the aspect ratio between the diameter of the hole and the thickness of the board is considered. If the thickness is 1.60mm, the hole size should be about 0.40. This means that the aspect ratio, in this case, is 1:4. Reducing the thickness of your PCB means that this ratio should also be reduced. 7.
