Why not just make it one shape, in different sizes?
In: Engineering
Let’s say an industrial buys their initial screws and tools from company A instead of B because at the time it is more advantageous. Later on, the industrial needs more screws and at this point B seems more advantageous. Thing is, you bought your tools from A and they are not compatible with the screws from B so you are highly encouraged to pursue business with company A. Company A ensured that you would keep doing business with them by making their products non compatible with other companies.
Another reason is the reluctance that industrial have towards letting their customers repair their own products. They would rather have you buy a brand new one. If you don’t have the proper tools you might quickly get discouraged from trying to open, investigate and repair your broken possessions, you are more inclined to dispose of it and purchase a new one or to send it to the manufacturer for them to repair it.
I am sure there are other reasons, the thing is to put yourself in the shoes of those that benefit from this.
