This Hart 20 piece Screwdriver set is perfect for all purposes around the house & yard, mechanical repairs, construction & assembling things and comes with all standard sizes needed. My #1 favorite feature is the large, easy-to-see tip identifiers (IDs) that are on the heads of each driver, so you are not having to guess and can pick the right one the first time!! The IDs show the size & type (shape) of tip it is.
The 6-in-1 screwdriver is very handy to have on hand & on-the-go, for projects you're not sure what tips you'll need. The magnetic tips do hold strong.
The 6 precision screwdrivers, for much smaller uses, come in a storage case which has tip SIZE labels imprinted on each driver's assigned slot & the heads of each driver IDs the TYPE (or shape) of tip it is. A complete standard sizes set for all your everyday needs.
