Ampco Striking Wrench, Aluminum, Bronze, Natural, Head Size 4", Overall Length 17", 0 °

Nonsparking striking box-end wrenches won’t spark during use, making them suitable for use in flammable environments. A block shape on one end of the handle is struck with a hammer to loosen or tighten a fastener. The opposite end has an enclosed head end (box end) that fits around the entire head of the fastener for a more secure grip while turning compared to an open end. These SAE (inch) size wrenches have a straight handle and a 12-pt. design with additional grooves that make it easier to connect with the head of the fastener and connect at more angles for better accessibility compared to a 6-pt. wrench.
