WHEELER ENGINEERING - F.A.T. AutoTorque Wrench Gray/Black

Wheeler Engineering F.A.T. AutoTorque Wrench - Digital Precision, Every Single Time

The Wheeler Engineering F.A.T. (Firearm Accurizing Torque) AutoTorque Wrench is the next evolution in gunsmithing torque tools-designed for those who demand fast, repeatable, and highly accurate fastener installation without the margin for human error. It brings together the speed of a power driver, the exactness of digital torque control, and the rugged reliability shooters expect from Wheeler. Whether you’re an optics installer, a precision rifle tuner, or a professional armorer, this wrench will change the way you work.

Purpose-Built for Precision Torque

Unlike mechanical “click” style torque wrenches that rely on manual feel, the AutoTorque Wrench integrates a digitally controlled, motor-assisted torque system. You simply set the desired torque value-anywhere between 10 and 65 in-lbs-on the digital interface, and the wrench delivers it exactly, stopping automatically at your set point. No second-guessing, no over-tightening, and no misreading torque charts.

This level of control is especially critical for firearms work, where an extra inch-pound can mean the difference between a properly bedded scope and one that walks out of zero after a few hundred rounds. With the AutoTorque, consistency is baked in from the first fastener to the last.

Designed for Speed and Efficiency

The AutoTorque Wrench’s variable-speed motor delivers up to 200 RPM, meaning it can spin fasteners down quickly before automatically slowing as it approaches the torque threshold. A dedicated MAX power mode allows for removing stubborn screws or bolts without risking the wrench’s calibrated torque setting.

In the shop, this means less time spent fiddling with tools and more time building, adjusting, or testing your firearm. At the range, it allows rapid adjustments between strings without fumbling with manual torque tools.

Visibility and Comfort in Any Environment

Wheeler built the AutoTorque with four high-intensity integrated LED lights that illuminate the work area directly in front of the bit-ideal for scope base screws tucked under turrets or fasteners hidden inside chassis systems. The ergonomic handle provides a secure, comfortable grip even when wearing gloves, ensuring full control during delicate adjustments.

The unit’s balanced weight and compact size make it comfortable for extended use and easy to maneuver into awkward angles-a common requirement when dealing with firearm assemblies.

Battery-Powered Freedom

A rechargeable 12V lithium-ion battery powers the AutoTorque, offering hours of use on a single charge. The battery is removable for quick swaps and recharges via USB-C, so you can power it from wall outlets, portable chargers, or even vehicle USB ports in the field. An easy-read LED battery indicator keeps you aware of remaining charge at all times.

Multiple Use Cases in Firearms Work

The Wheeler F.A.T. AutoTorque Wrench excels in a wide range of applications:

• Scope Ring Mounting – Ensures even clamp tension to maintain zero and prevent optic shift.
• Action Screw Installation – Delivers precise torque for bedding consistency in bolt-action rifles.
• Chassis and Rail Systems – Keeps alignment true on M-LOK, KeyMod, or proprietary mounting platforms.
• AR Platform Builds – Perfect for accessory mounting where inch-pound precision is critical.
• Maintenance and Travel – Ideal for torque verification on firearms after transport or extended storage.

Real-World Feedback from the Field

Shooters who have adopted the AutoTorque Wrench consistently report that it saves them time without sacrificing accuracy. Many appreciate that the digital readout confirms torque values in real time, removing the guesswork that sometimes comes with traditional click wrenches.

Optics installers in particular note that the AutoTorque prevents scope ring overtightening, which can damage tube bodies or distort optics internals. Competitive shooters value its speed when adjusting mounts or accessories between stages, while hunting guides like its portability and field-ready charging options.

In shop use, some armorers mention that having one AutoTorque Wrench has replaced the need for multiple mechanical torque tools, freeing up bench space while increasing workflow speed.

Built for the Long Haul

While compact and user-friendly, the AutoTorque is built on a robust frame with reinforced internals to handle repeated torque cycles without calibration drift. Wheeler’s engineering focus ensures that even after hundreds of uses, the wrench maintains accuracy-critical when working on customer firearms or expensive optics.

The storage case is equally well thought out-rugged, stackable, and molded to secure the wrench, bits, and accessories in transit. This makes it easy to keep everything organized and protected whether you’re heading to a competition, range day, or backcountry hunt.

Why the AutoTorque Wrench Belongs on Your Bench

Firearms assembly and maintenance demand tools that deliver repeatable performance under precise tolerances. The Wheeler Engineering F.A.T. AutoTorque Wrench brings the accuracy of a professional torque system together with the convenience of a cordless driver for eliminating errors, increasing speed, and improving build quality.

From a benchrest shooter fine-tuning a precision rifle to a field armorer servicing multiple rifles in one session, the AutoTorque delivers results that manual tools can’t match. Once you experience its speed, accuracy, and ease of use, going back to a standard click wrench will feel like a step backward.

This isn’t just a torque wrench, it’s a workflow upgrade.
