Beta Tools highlighted its offset hex key wrench, which has an extra-short end which is angled at 110 degrees, to provide access where traditional 90-degree angled wrenches cannot reach. The short end is shallow to allow it to reach tight spaces. The long end has a ball-end hex which allows you to turn fasteners at an angle up to 30 degrees. The #96BPA hex key wrench comes in 9 metric sizes: 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm.
