Proto Industrial Tools, a division of Stanley Black and Decker, is a leading manufacturer of industry-grade torque tools, cutting tools, finishing tools and fastening tools. The Proto Tools catalogue includes a wide range of sockets, wrenches, ratchets, screwdrivers, hex keys, pliers, snips, clamps, master sets, punches, chisels and tethered tools. Handheld punches and chisels from Proto are designed to remove pins and bushings, as well as cut or split steel objects. These units feature a highly-modified parabolic striking end to prevent mushrooming and chipping. They further come with a polished panel, marked with the tool number and size, for easy identification. The brand's steel / alloy steel crowfoot wrenches have an anti-slip design and are ideal for low-torque applications where standard wrenches or ratchets cannot be used. Choose from a wide range of these quality wrenches and other company products, such as socket bits, hand-held punches and chisels, on Raptor Supplies.
