The Blackhawk by Proto Quick Ratchet tool sets let any assembly, maintenance, or repair technician enjoy the benefits of a tool technology once found only in precision torque wrenches. This system revolves around a ratchet handle that accepts interchangeable working heads, including ratcheting box wrenches, 3/8- and 1/4-inch socket drivers, and a screwdriver bit driver. It includes a precise positioning head that rotates through 180 degrees, locking every 12 degrees in 15 different positions. It can be used as: a flexible ratcheting box wrench in 13 common SAE and metric sizes, a standard ratchet, able to accept any 1/4 or 3/8 in drive socket, ratcheting screwdriver or standard screwdriver. The interchangeable heads easily snap onto the handle. The handle's slim profile and flexible head, combined with the short sweep of the ratcheting heads, make it easy for workers to access and turn fasteners in hard-to-reach spots. Each set includes a low-profile, knurled screwdriver bit driver that can be snapped onto a ratchet head, or removed and turned by hand. When hand-turned, the knurled driver helps let workers easily turn screws that might be too small for even the shortest screwdriver to squeeze into. Quick Ratchet sets can be used for multiple types and sizes of fasteners and comes in a compact, 8.5- by 12-inch case. For more information visit www.stanleyproto.com or call (800) 800-TOOL.
