McMaster 5314A51 Polished Chrome-Plated Combination Wrench, 12-Point Opening, 10 mm Size, 6-1/8" Overall Length
Your go-to wrenches for routine maintenance. With two different ends, you need fewer tools to tighten and loosen nuts and bolts. The open end slides onto the side of fasteners for adjustments in tight spots. When nuts and bolts won't budge, the box end fully encircles them to apply maximum torque. Drop forged for added strength, these wrenches will be part of your toolbox for life.
12-Point Opening — The most common opening, these wrenches work on hex and 12-point nuts and bolts. They slide onto hex heads at more angles than 6-point fasteners for quicker engagement.
Chrome-Plated Steel — The most popular finish, these wrenches won't rust or chip.
Polished — The smooth surface is easy to wipe clean of grime. The mirror-like finish lends a high-end look to any toolkit.
