Tekton shallow and deep 6-point sockets are ideal for working with hex-shaped fasteners. They're designed to grip the sides and not the corners of the fastener heads, which prevents round-off. The large, die-stamped markings are permanently impressed into the material and optimized for readability. This set includes carrying case made of a high-density polyethylene material that withstands exposure to common lubricants, fuels, and solvents.
