4.0mm Ball Driver for M5 Cap Screws

The 4.0mm ball driver is the correct size driver to use for standard M5 cap screws. The ball end drivers have a rounded tip allowing them to be used at an angle making them a great choice for tightening and loosening screws in hard to reach places.  Ball End inserts into screw at a up to a 25° angle.

US (imperial) ball drivers have a black ergonomic molded cushion grip handle with a yellow handle top while metric ball drivers have the same handle with a red top. Two component handle with tough inner core and cushioned rubber exterior makes these ball drivers an upgrade from the standard hard plastic ball drivers typically found in labs.
