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.

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.

Black-Oxide Steel—The dark, matte coating protects these wrenches from wear and won't flake off. They offer minimal corrosion resistance, though, so they're best for dry environments.

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.

Deep-Offset High-Leverage Box Wrenches

A 45° offset head provides clearance for reaching over obstructions. These wrenches have a long handle for extra leverage—add an extension to increase it even more.

Extension Handles—Extension handles (sold separately) fit securely over the end of the wrench.

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.

Striking Box Wrenches

12-Point Opening

Also known as slugging wrenches, strike the handle with a hammer to break stuck fasteners free.

12-Point Opening—Wrenches with a 12-point opening are easier to position on hex fasteners than wrenches with a 6-point opening but make less contact.

Backup Box Wrenches


	Head and Handle Sold Separately

When you’re working with high torque, these wrenches keep the nut from turning as you tighten a bolt. You'll need a head and a handle to form a complete wrench. The head goes around the nut you want to hold stationary and the handle braces against an adjacent nut, absorbing the torque. They're often used when sealing large pipe flanges with a hydraulic torque wrench. Safer than striking wrenches, they stay securely on the nut until you release them.

Opening

Made of aluminum bronze that is FM approved, these wrenches won't create sparks even when scraped, struck, or dropped. They help you meet OSHA requirements when turning nuts and bolts in hazardous environments with flammable vapors, liquids, or dust. Use them everywhere from oil refineries to chemicals plants.

Warning: Do not use these tools in direct contact with acetylene.
