Bondhus invented the Balldriver — the ball-end hex key that lets you engage a fastener at an angle up to 25 degrees off-axis — back in 1964 in Monticello, Minnesota, and the company has been producing hex tools in that same Midwestern facility ever since. Every wrench is cold-formed from proprietary Protanium high-torque steel, then heat-treated for a 20-percent torque advantage over standard alloy steel.
The 13390 is a 10-piece T-handle set with a stand that holds each driver upright at the bench — reach for the size you want without digging through a pouch. The T-handle design lets you spin fasteners fast on the pull-out and apply cross-handle leverage on the final tightening turn. Every tip is Protanium steel for torque and wear life.
Bondhus has been family-owned and American-made in Monticello, Minnesota since 1964, where they still machine and heat-treat every Balldriver and hex key on site. The company backs the full line with a lifetime guarantee against manufacturing defects.
