McMaster 5314A26 Polished Chrome-Plated Combination Wrench with 12-Point Openings, 11-Piece Metric Set

With a range of drive sizes and lengths, these wrench sets are your go-to 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.

Industrial—Made in the U.S. from high-strength steel or stainless steel, these wrenches are built to last. They’re indispensable for daily maintenance and repair.

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, but they're more likely to slip when you apply more torque.

Polished—The smooth surface is easy to wipe clean of grime. The mirror-like finish lends a high-end look to any toolkit.

Chrome-Plated Steel—The most popular finish, these wrenches won't rust or chip. Although they withstand moisture better than black oxide, they don't hold up to harsh chemicals as well as stainless steel.
