The M7 MA831M33 impact deep socket has a 35mm head. It attaches to most air impact wrenches that have a 1” drive. Snap it on your M7 air tool then get to work loosening and tightening those 35mm fasteners that other sockets can’t reach. You don’t have to worry about the torque, either. This deep well socket features a Chromium-Molybdenum steel construction. This helps it resist the corrosion and flaking that can be common under torque. The MA831M33 features a six-point head. The tool style connects to the fastener head at its thickest part, away from the corners. This reduces the chance of slippage, which tends to round or strip fastener corners. Anyone who has removed a stripped bolt will appreciate a deep impact socket that prevents this from happening.
