25 mm Wrenches | McMaster-Carr

With the flick of a lever, the wrenches in these sets go from loosening nuts and bolts to tightening them. Unlike other ratcheting wrenches, you can turn in either direction without having to flip them over. They're ideal for jobs with frequent pivots between tightening and loosening, such as assembly line maintenance.

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.

Value—Fill out your tool kit for a few dollars per wrench. Typically imported, these cost-friendly sets are the right choice for occasional maintenance.

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.

Combination Wrenches

12-Point

Opening

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.

Dull—With a textured finish, these wrenches won't slip out of your hands, even when greasy or oily.

Wrench Heads


Wrench and Socket Extension Not Included

Reach nuts obstructed by a fluid line or other barrier with these wrench heads. Connect them to your socket extension and ratchet wrench to turn fasteners where clearance is limited from both the top and side. You can also attach one directly to your ratchet wrench to convert it into an open-ended ratcheting wrench. Also known as crowfoot wrenches.

Spanner Sockets


Socket Shown With Wrench (Sold Separately)

4-Pin

For easy tightening and loosening, these sockets have pins that grip the slotted sides on bearing nuts. These sockets require less clearance around bearings than standard hook spanner wrenches, so they’re good in tight spaces. Use them with a square-drive wrench handle or a ratchet wrench; they’re not for use with impact wrenches.
