Non-sparking 6-point socket in aluminium bronze for 9/16 inch fasteners, FM approved to ASTM A342
This 1/2-inch drive SAE socket fits 9/16-inch fasteners and is machined from aluminum bronze to eliminate spark risk. FM Approved certification confirms compliance for use in flammable or explosive atmospheres where standard steel tools are unsafe.
The socket meets ASTM A342 and carries FM Approved status, the single specification that qualifies it for regulated hazardous-area work. Without this certification the tool cannot be used in many industrial safety programmes.
The six-point opening engages the full flats of a 9/16-inch hex head, reducing rounding on soft or corroded fasteners. It is rated for hand use only and is not impact rated, so powered drivers will exceed its design limits.

The 9/16-inch hex opening matches SAE fasteners of that exact size, giving a precise fit on nuts and bolts with a 9/16-inch across-flats dimension.
The 1/2-inch square drive only accepts ratchets, breaker bars or extensions with a matching 1/2-inch male drive, so smaller 3/8-inch or larger 3/4-inch tools will not connect.
The six-point aluminum-bronze wall thickness requires enough side clearance for the socket to slide straight over the 9/16-inch hex without obstruction from adjacent components.
