Snapon SBX1820 9/16-5/8inch flank drive

size: 9/16-5/8inch

A Snap-on SBX1820 wrench covers both 9/16 and 5/8 inch fasteners with its double-ended S-shape. The Flank Drive system increases turning force by 15–20% while reducing fastener damage. Each end uses a 12-point configuration for better grip on hex heads. The alloy steel construction and nickel-chrome finish resist corrosion and wear in professional garages.
