The 96BPA series of ball end Allen hex keys are designed for professional use with a satin-finish chrome plating that wipes down easily after use. The short leg and the extended leg of the L-handle both have the same size metric hex. The hex at the end of the extended leg has a ball profile to allow for insertion for up to a 30 degree angle, and the extra-short end is angled at 110-degrees making it easier to reach fasteners in confined or obstructed areas. Ideal for hard-to-reach bolts in machinery, automotive, furniture assembly, and electronics. This 9-piece set of hex keys includes a folding case that locks all the keys in place when you snap it closed. The interior of the case has a molded strip on each side and closing the case forces the strips against the keys to positively lock them in place. When you open the case, pressure is released and the case acts like an ordinary holder. This metric set includes sizes 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10mm.
