Twist And Fix Series. Yellow GRN handles. Instead of being housed in fixed, external bearings, each element in the tool set revolves around a central axle, lengthening the tool you need and keeping the others out of the way. They are held together with a low-profile frame, snapping in and out with ease so your workflow remains uninterrupted. Tools include: SAE Socket (1/4, 5/16, 7/16) and Metric Socket (6mm, 8mm, 10mm). Designed by Ryan Glasgow.
