Milwaukee 2966-20 M18 FUEL™ 1/2" High Torque Impact Wrench w/ Pin Detent

Maximized Pin-Detent Socket Retention. 1,100 ft-lbs Nut-Busting Force. Compact 7.3" High-Access Frame.

The Milwaukee 1/2" High Torque Impact Wrench with Pin Detent bare tool introduces relentless structural driving power, maximum secure socket containment, and intelligent electronic bolt control straight to your commercial infrastructure setup. Purpose-built to break free stubborn, rusted, and over-torqued heavy fasteners without forcing you to pull stiff, freezing air lines up onto high scaffolding towers, this cordless brute unleashes up to 900 ft-lbs of Max Fastening Torque and a massive 1,100 ft-lbs of Nut-Busting Breakaway Force. It provides structural steel framing crews, power line linesmen, industrial millwrights, and civil highway contractors with an elite 18-volt handheld platform optimized to anchor structural bolts, tighten lag shields, and secure overhead infrastructure safely.

Uncompromising high-altitude user safety and advanced precision management form the foundation of this next-generation M18 FUEL™ powerhouse. Measuring a mere 7.3 inches in overall length, this compact, power-dense tool easily navigates crowded utility poles, narrow bridge joints, and tight industrial subframes. It is engineered with a specialized 1/2-inch square drive pin-detent anvil, a premium retention system that uses a physical spring-loaded steel pin to mechanically lock impact sockets to the shaft. This completely eliminates the hazard of heavy sockets spinning off or plunging down into active lower-tier workspaces. To handle repetitive high-load fastening cycles, it features an integrated 4-Mode DRIVE CONTROL™ selector with an automated Bolt Removal Mode. This smart board delivers full breakaway torque up front to snap rust bonds, then slashes motor speeds instantly once friction releases to stop fasteners from spinning loose and dropping.

Why the Milwaukee 2966-20 M18 FUEL™ Pin-Detent Gun Controls the Catwalk:

• Absolute Pin-Detent Safety Retention: Mechanical locking pin anchors impact sockets securely onto the square anvil, preventing dropped tools during high-elevation tasks.
• Ruthless 1,100 ft-lbs Breakaway Torque: Powerful brushless drive shatters stubborn rust scales and seats heavy lag hardware with pure cordless force.
• Power-Dense 7.3-Inch Short Body: Ultra-compact housing maximizes physical leverage while letting users slip into tight structural iron configurations smoothly.
• Vibration-Isolated Battery Dock: Patented internal rubber terminal isolation cushions protect battery slots from fracturing under continuous concrete anchoring shocks.
• Shadow-Free Tri-LED Zone Lighting: Three high-brilliancy LEDs ring the nose shroud to illuminate dark framework joints cleanly without casting hand shadows.
