The original design had indents in the plugs to allow them to stay tight in the outlet. Others worked around the patent by drilling holes that could be used for the same purpose. Most outlets today use a “squeeze to hold” type of connection, but some still make use of the holes if there are there.

According to How Stuff Works there are three main functions of these two little holes. Reason #1: grip. If you were to get a look inside an outlet after a plug goes inside of it to get juice, you’d notice that the contact wipers used to communicate an electric current have little “bumps” on them.

The third reason why electric plugs have holes in them is probably the one that manufacturers like the most. It's because it ultimately saves them money in raw materials. If you're mass producing a bunch of these little prongs, think about the metal you gather from those little punch-outs.

There are three reasons for the holes: If you were to take apart an outlet and look at the contact wipers that the prongs slide into, you would find that they have have bumps on them. These bumps fit into the holes so that the outlet can grip the plug's prongs more firmly.

The presence of the holes allows the plug to fix in the socket with great ease and with a firmer grip, ensuring a secure connection. Ensures safety: Another benefit of having these holes in the electrical prongs is that the manufacturer can provide detailed instructions on a tag. They can attach this tag inside the hole. Such a process ensures that the user cannot plug in any device without removing those tags from the hole.

An expert at Underwriters Laboratories says the holes are a by-product of the manufacturing process: they’re needed to hold the prongs in place while the plastic part of the plug is molded around them. A guy from General Electric, however, says the purpose of the holes is to dissipate the heat generated by the flow of electricity.

Some surmise that the holes were made to fit an electrical lockout. But seeing that lockouts were first introduced in the 50s, 40 years after the first electrical plug was introduced, this doesn’t seem to be the case. Another farfetched explanation is that the excess metals from the holes were used to support the war effort.
