The Great Neck® Hex Key Fold-Up Tool Set is the perfect addition to your toolbox! Key tines are precision ground for accuracy and polished with a rust- and corrosion-resistant black-oxide finish. The body of each fold-up tool is also clearly color-coded, so it can be easily identified and retrieved. Durable composite construction ensures a longer, productive life even when extended, rugged-environment use is the norm. Two hex-key adjustable tangs allow you to tailor the fold-out action of the tines to achieve a customized feel.
