This tool is meant to fit the fastener cleanly and let you work in the kind of access you actually deal with on a bench, in a panel, or under equipment. The size and shape matter because they decide whether the tool seats properly and whether the work turns into a fight.
Bondhus builds these with working mechanics, electricians, and maintenance techs in mind, so the point is straightforward: reliable fit, enough leverage, and no drama when the fastener is buried or stubborn.
