Quality hex key set with black ProGuard™ finish. Comes with dual ball-end sides. Short side allows a 15° work angle, the long side up to 25°. The Stubby’s short side is extra short, angled at 100° and has a special, extra tight, inside radius which improves bolt-head insertion right after the bend. This allows you to work in spaces with tight overhead clearance where regular hex keys, even when shortened, have no access. Manufactured from US made Protanium™ industrial high torque steel. Comes complete with plastic holder. 13 piece kit Double ball end. Includes .050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8″.
