AMPCO Striking Wrench Straight

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 6-pt. design that allows more contact with the fastener's sides than the 12-pt. style and prevents rounding the fastener's corners.
