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".
