Name that company

I trace my roots back to 1843 and 1910, when the founders of two companies got their starts — respectively setting up a hardware factory in New Britain, Connecticut, and a machine shop in Baltimore. Those companies would eventually merge in 2010. Today, with a market value recently near $27 billion, I employ more than 60,000 people in the world’s largest tools and storage business. I’m also involved in electronic security services, infrastructure, oil and gas — and even health care. My brands include Bostitch, Craftsman, Dewalt, Irwin, Lenox, Mac Tools and Porter Cable. I’ve paid dividends for 144 consecutive years. Who am I?
