Hand tools and power tools are used on jobsites and in production facilities to measure, cut, fasten, and form materials. Hand tools include clamps, cutting tools, measuring tools, hammers, screwdrivers, and wrenches. They provide precise control and are used for tasks where power tools are cumbersome or where high amounts of force are not required. Power tools include cordless, corded, hydraulic, and air-powered drills, drivers, impact wrenches, saws, and finishing tools. They are used for tasks that are repeated (such as driving nails in sheetrock) or where high force and speed are required. Measuring and layout tools ensure workpieces are cut to the correct length and angle. Sockets and bits are used with wrenches, screwdrivers, and drills to create holes and drive fasteners. Tool tethers, balancers, and retractors secure tools to keep them close at hand when needed and help prevent injuries caused by dropped tools. Tool storage keeps tools secure and organized for quick access.
