32 mm nut wrench set - Why you need it - Designed for tight spaces where traditional sockets cannot fit, yet compatible with traditional large open-end wrenches or socket wrenches for versatile operation. - Provides a compact, easy to use solution that integrates with existing drive handles to extend your tool options. - Sizes included - 3/8 inch (medium) wrenches: 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm - 1/2 inch (large) wrenches: 21 mm, 22 mm, 24 mm, 27 mm, 28 mm, 30 mm, 32 mm - 19-piece set - The line wrench set contains 19 pieces of replaceable hexagonal open-end wrenches. - It is designed to be installed on some of the same drive handles as straight-through sockets, but the shape is not cylindrical, and its end is the same as the opening of these sockets or flare nut wrenches. - Material and durability - Made with a molybdenum steel quenching process, delivering high strength and ductility for a long service life. - Use scenarios - Automotive or machinery work in cramped engine bays where space is limited and standard sockets cannot reach. - When you already use drive handles for straight-through sockets, you can mount these line wrenches on the same handles for convenient operation. - Flare nut or hex fittings in tight or awkward locations where a non-cylindrical wrench end improves access and engagement.
