This 12-piece Astro Tools Razor Wrenches set covers metric sizes from 8mm to 19mm and features an ultra-thin profile that is up to 40% thinner than comparable ratcheting wrenches. Despite the slim design, these wrenches exceed ASME proof torque specifications for full-size wrenches. The set includes offset angled open-end heads and slim profile ratcheting ends with a 72-tooth mechanism, finished in satin chrome with a lifetime warranty.
