Wheeler FAT Wrench AutoTorque

• Integrated torque limiter: The AutoTorque stops when the selected torque is reached, helping prevent overtightening that can damage scope rings, bases, red dot mounts, and action screws.
• Battery-powered operation: The 12V system and up to 200 RPM motor speed let the tool handle repetitive mounting work faster than a manual driver, which is useful when setting up multiple firearms or optics.
• Digital torque adjustment: The LCD display sets torque from 10-65 in-lbs. in 0.1 in-lb. increments, making it easier to match manufacturer torque specs with repeatable precision.
• Built-in work lights: Four ultra-bright LEDs illuminate the fastener area, which helps when working inside actions, around bases, or on a crowded bench.
• Ready-to-use kit: The included 15-piece 1/4" bit set, rechargeable battery, and hard case keep the essential components together for transport, storage, and routine gunsmithing tasks.

About the F.A.T. Wrench Series

The Wheeler F.A.T. Wrench series is built around one core requirement in firearms maintenance: applying the correct torque to small fasteners that secure optics, mounts, and action components. Within Wheeler's gunsmithing lineup, the series sits as a dedicated torque-tool family for shooters, armorers, and hobbyists who need more control than a standard screwdriver can provide. It is commonly used for scope mounting, red dot installation, ring and base work, and other low-torque assembly jobs where consistency matters.

Across the range, the F.A.T. Wrench concept focuses on repeatable torque application, straightforward adjustment, and workshop-friendly storage. Different models in the family cover traditional manual operation, digital readout formats, and now powered operation for faster work. What distinguishes the series is its emphasis on firearm-specific tasks rather than general household fastening. That makes the tools especially relevant for hunting optics and precision shooting setups, where uneven or excessive torque can affect both reliability and zero retention. The result is a product family designed to make careful mounting work more consistent, whether the job is done at a bench, in an armory, or during routine maintenance.

About the Wheeler FAT Wrench AutoTorque

The Wheeler FAT Wrench AutoTorque brings powered convenience to a task that normally demands slow, deliberate hand work. It is a battery-operated screwdriver with an integrated torque limiter, designed specifically for gunsmithing jobs such as installing red dots, tightening scope bases and rings, and securing action screws. In practical use, that means faster assembly without giving up the control needed to protect optic mounts and firearm components from excess torque.

The tool adjusts from 10-65 in-lbs. and shows the selected setting on an digital LCD display in 0.1 in-lb. increments. That fine adjustment is useful when following manufacturer torque specifications closely, especially on modern optics mounts where a few inch-pounds can make the difference between a secure fit and a damaged fastener. Once the selected value is reached, the motor stops automatically, which helps keep torque application consistent from screw to screw.

A variable-speed trigger and up to 200 RPM motor speed make repetitive work quicker, while the max setting helps break loose stubborn fasteners. The detachable 12V lithium-ion battery uses USB-C charging and supports up to 2 hours of continuous runtime, making the tool practical for bench use or range-bag setup sessions. Four built-in LEDs improve visibility around small screws and recessed mounting points, and the included 15-piece 1/4" bit set covers many of the common fasteners found on current firearms. Packed in a premium latching hard case, the AutoTorque is organized for storage and transport rather than loose-bench use.
