I was in a friend’s garage recently helping him with a home-improvement project when I noticed that many of the wrenches and sockets in his tool cabinet were wrapped in red electrical tape. On closer inspection, I noticed that the colored tape was only wrapped around his metric-sized tools.
By having an easy way to differentiate his metric tools from their SAE counterparts, he found he was more likely to put both types back in their correct places when he was done using them.
Do you have any tricks for labeling things to keep them grouped with similar items? Please share them in the comments.
