McMaster 4019N9 Black-Oxide Steel Adjustable Wrench Plain Grip, 3 Piece Set, 1-3/8" Jaw Capacity

Tighten or loosen a range of fastener sizes with a turn of the thumbwheel. These wrench sets are salt spray tested and drop tested to meet SAE AS4984, so the coating won’t rust, crack, or chip. Drop-forged from alloy steel, they'll stick around your toolkit for years.

Black-Oxide Steel—The dark, matte coating won't wear down or flake off as easily as painted steel, but only resists occasional moisture.
