The screw key is a keyring attachment and a convenient way to fix something on the go. Carrying around an actual screwdriver or a toolbox is not practical for daily life, but these screw keys are the perfect way to give yourself some options when you're out and about if something needs to be fixed.
Although many keychain attachments are designed to be multi-purpose items, each individual screw key is made to do just one job and do it well. The keys are constructed of heat-treated black steel, which makes then durable and long-lasting.
Although these screw keys don't have a handles, there is still enough length to get a grip on. In a pinch, these portable tools could be very useful to have on hand.
