The Capri Tools Sliding T-Handle Hex Key Wrench is built to satisfy even the most demanding professionals. It has a sliding top bar and 3 hex ends, letting you maneuver easily in tight spaces and adapt quickly to apply the most torque possible. Premium Chrome Vanadium steel cross bars, each forged from a single piece steel, are built to last and perform in high torque situations. Precision machined hex end with chamfered edges fits smoothly onto fasteners and prevents rounding. There are 3 detent balls to keep the sliding handle secure. The center spring-loaded detent ball clicks the handle in place at the center T position. 2 end detent balls keep the handle secure at L positions. We completed the t-handle wrench with our premium Satin chrome finish, our most sophisticated finishing and coating profess. Satin chrome not only enhance durability, but give the t-handle an unparalleled look and feel. All 3 hex ends are sized 10 mm.
