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 45207 is a single 1/8-inch T-handle hex driver with a six-inch shaft — the T-handle form lets you spin fasteners fast between your fingers on the pull-out and then set torque with the cross handle on the final turn. The Protanium steel tip holds its shape under load instead of rounding, and the balanced handle sits between palm and fingertips so the shaft stays parallel to the fastener.
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.
