29 mm Wrenches | McMaster-Carr

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

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.

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

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

Universal-Fit Sockets

Turn multiple shapes and sizes of fasteners with a single socket. Use these on hex, square, and other external-drive fasteners—even wing nuts. Place the socket over the nut or screw head and the 54 pins move to grip it securely. For use with hand-drive tools only.

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.

Ratcheting Box Wrenches

12-Point Opening

A ratchet mechanism allows you to turn fasteners in tight spaces without removing and repositioning the wrench.

Turn Required to Ratchet—The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.
