3 mm Metric Ball Hex Key

This 3 mm metric ball hex key is designed for mechanics and technicians who need reliable access to hex fasteners in tight or angled spaces. The ball-end on the long arm allows engagement at an angle, while the short arm provides leverage for high-torque applications. It is made from corrosion-resistant stainless steel for durability in demanding environments.

6 in Long Arm and 3 in Short Arm

The 6 in long arm offers extended reach for deep or recessed fasteners, while the 3 in short arm fits confined areas where a longer tool cannot turn. The non-magnetic finish prevents unwanted metal shavings from clinging to the tool during use. This key does not feature a tether point or insulated coating, so it is not suited for height-safety or live-electrical work.

Questions about this item

Will the 3 mm tip fit the socket-head screws I already use on my metric equipment?

Yes, the 3 mm hex tip matches standard metric socket-head screws, so it will engage the fasteners you currently have.

How can I check the key is working correctly after I start using it?

Insert the ball end into a 3 mm socket screw; it should engage smoothly at an angle and turn the fastener without rounding the corners.
