Torque Wrenches

Adjustable Torque Wrenches

Set the desired torque and the wrench indicates when it's reached with an audible click and an impulse in the grip.

Nonsparking Torque Wrenches

Made of beryllium copper, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Click-Style Factory-Set
Torque Wrenches

When the set torque is reached, these wrenches signal with an audible click and an impulse in the grip.

Slip-Release Factory-Set
Torque Wrenches

These wrenches slip to disengage and stop turning the fastener when the set torque is reached, preventing overtightening.

T-Handle Slip-Release
Factory-Set Torque Wrenches

Turn sockets from above when there's not room to swing a standard wrench handle.

High-Accuracy
Torque-Measuring Wrenches

Trust the precision of your measurements—these wrenches are accurate to ±1%.

Combination Wrenches

Ratcheting Combination Wrenches

Flip these wrenches over to ratchet in the opposite direction.

Reversible Ratcheting
Combination Wrenches

A lever reverses the ratchet direction.

Spline Ratcheting
Combination Wrenches

A spline-shaped box end turns spline, hex, and 12-point fasteners. This shape also gets a better grip on rounded fasteners that can be difficult to turn with a traditional wrench.

Made in the U.S.A., these tools handle the toughest industrial applications, provide the best grip on fasteners, and have a superior finish.

Spline Ratcheting
Combination Wrench Sets

A spline-shaped box end turns spline, hex, and 12-point fasteners. This shape also gets a better grip on rounded fasteners that can be difficult to turn with a traditional wrench.

Box Wrenches

Ratcheting Box Wrenches

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

Two-Head Ratcheting Box Wrenches

Ratchet mechanisms allow you to turn fasteners in tight spaces without removing and repositioning the tool.

Two-Head Deep-Offset
Ratcheting Box Wrenches

The 25° offset heads give you additional clearance to turn hard-to-reach fasteners.

Ratcheting Box Wrench Sets

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

Deep-Offset Ratcheting
Box Wrench Sets

The heads are offset to provide clearance for reaching over obstructions.

Snap-Open Ratcheting
Box Wrench Sets

Open the jaws to fit around a fastener like an open-end wrench; close the jaws and the wrench acts like a ratcheting box wrench.

Adjustable Socket Wrenches

Slide the lever to adjust the jaws to fit multiple sizes of square and hex fasteners.
