Adjustable Torque Wrenches


Ratcheting	Nonratcheting

Set the desired torque within range and these wrenches will signal when it's reached. To relieve pressure on the spring and maintain calibration, set torque to the lowest reading on the scale when not in use. These wrenches come with a calibration certificate, which includes test measurements that confirm accuracy.

Torque-Limiting Click—An audible click lets you know when the set torque is reached.

Torque—You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

Dial Torque-Measuring Wrenches

A main pointer on the dial shows torque as it’s being applied and a memory pointer indicates the maximum torque reached. Use to determine fastener torque specifications as well as to identify the torque required to loosen tightened fasteners. These wrenches come with a calibration certificate, which includes test measurements that confirm accuracy.

Note: Accuracy ratings do not apply to the lower 20% of the torque range.

Sealed-Head Adjustable Torque Wrenches

Keep lubrication in and contaminants out to extend tool life. These wrenches have a gasket that seals in permanent lubrication and blocks out dirt, dust, and moisture to protect the ratcheting mechanism.

Set torque within the range and these wrenches indicate when it's reached with an audible click. To relieve pressure on the spring and maintain calibration, set torque to the lowest reading on the scale when not in use.

Air-Powered Impact Wrenches


Pistol Grip	D-Handle Grip

Ring Socket

Retainer

Loosen stubborn fasteners—these wrenches operate at full torque counterclockwise to break stuck bolts free. You can also use them clockwise within their working torque range to tighten fasteners more quickly than with manual wrenches. Use these wrenches with impact sockets only. Air-powered tools require lubrication to operate properly.

D-Handle Grip—D-handle grip wrenches are heavier than straight or pistol grip wrenches, so you need to use two hands to deliver their full power.

Ring Socket Retainer—Ring-style socket retainers are good for quick socket changes—just pull the socket off the retainer and push on another one.

Ring and Hole Socket Retainer—Ring-and-hole and hole-style socket retainers hold sockets more securely than ring-style retainers and require a retaining ring. Hole-style socket retainers are also known as positive locking retainers.

Hole Socket

Retainer

Built to withstand tough environments, these wrenches have steel or titanium housings to protect them if they fall. Use them when you need high force to turn fasteners. To break stuck fasteners free, apply full torque counterclockwise. To drive fasteners, turn them clockwise within the working torque range. These wrenches can only be used with impact sockets. Air-powered tools require lubrication to operate properly.

Ring and Hole Socket Retainer—Ring-and-hole style and hole-style socket retainers require a retaining ring (not included).

Striking Square Drive Impact Wrenches

Take a swing and hit these wrenches with a hammer to generate the extra torque you need to break stuck fasteners free. Also known as slugging wrenches. Attach an impact socket (sold separately) that matches the square drive size.

Cordless Impact Wrenches


Pistol Grip	Ring and Hole Socket Retainer

Loosen stuck fasteners and drive in fasteners with high force anywhere on your site. These impact wrenches run on a rechargeable battery, so you don’t need to be near an outlet to use them. Wrenches operate at full torque in the counterclockwise direction. The working torque range applies to the clockwise direction, often used for fastening. Use these wrenches with impact sockets only.

Some wrenches come with batteries and a charger. For others, batteries and chargers are sold separately.

Ring and Hole Socket Retainer—Ring-and-hole-style socket retainers, also called positive-locking socket retainers, provide a more secure hold than ring-style retainers. These retainers require a retaining ring (included).

Air-Powered Torque Wrenches

Faster than manual torque wrenches, these run on air to turn fasteners quickly. Also known as nutrunners, they secure screws and nuts without the risk of overtightening. Set your desired torque and the wrench signals when it’s reached by stalling the motor or disengaging the clutch.

Use with impact sockets only. Air-powered tools require lubrication to operate properly.

Pistol Grip


Pistol Grip Shown in Use with Shock Absorber

These wrenches have a hole-style socket retainer that requires a retaining ring. All include a shock absorber you position against a nearby stationary object to prevent wrench kickback once the fastener is tightened. They also come with a calibration certificate.

Cordless Torque Wrenches

No outlets to find or cords to limit mobility—take these battery-powered wrenches wherever they’re needed. Use them to secure nuts and bolts without the risk of overtightening. Set your desired torque and the wrench signals when it’s reached with an indicator light, audible click, or by stalling the motor. All come with a calibration certificate, which includes test measurements that confirm accuracy.

Wrenches with a _3/4" or larger square drive are only for use with impact sockets.

Pistol Grip with Hole Socket Retainer


Pistol Grip Shown in Use with Shock Absorber		Hole Socket Retainer

These retainers require a retaining ring to hold them firmly in place. Also known as positive locking retainers, they’re more secure than ball-detent style.

Shock Absorber—Position these shock absorbers against a nearby stationary object to prevent the wrenches from kicking back once your fastener is tightened.

No-Reset Adjustable Torque Wrenches

Unlike most torque wrenches, you don’t have to set torque to the lowest value on the scale after use. These wrenches indicate when your set torque is reached with an audible click and an impulse in the grip. They come with a calibration certificate traceable to NIST, which includes test measurements that confirm accuracy. Also known as split-beam torque wrenches.

Standard Head

Torque—You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

Repair Kits—Include the components needed to replace a damaged ratcheting mechanism.

Breaker-Bar Handles—Breaker-bar handle (sold separately) attaches to the head of your torque wrench to break stuck fasteners free without risking damage to the wrench. It extends for additional length.
