Sixcow 1/2-Inch Drive Weighted Crank Bolt Socket Set — 17mm–27mm (6-Piece) Harmonic Balancer Kit

Overview

Meet Sixcow’s 1/2-inch drive weighted crank bolt socket set, engineered to channel momentum where you need it most. The weighted design directs energy toward stubborn crankshaft bolts and harmonic balancers, helping you work more efficiently with compatible impact wrenches. Precision-made for durability and grip, these deep sockets are a practical upgrade for any toolbox.

The set includes six metric sockets—17mm, 19mm, 21mm, 22mm, 24mm, and 27mm—plus a compact storage case. This selection offers broad coverage for a variety of makes and models, making it a versatile addition to professional and DIY setups alike.

3x Momentum Power

By delivering momentum-driven torque, the weighted sockets aim to reduce the need for repeated passes and awkward repositioning. Real-world use in tight spaces can feel steadier, with improved control when breaking free stubborn fasteners behind pulleys or near the crank area.

• 3x momentum power compared to standard impact sockets for more effective torque delivery.
• Heavy-duty, drop-forged alloy steel with heat treatment for lasting strength and durability.
• 6-point design helps lock fasteners firmly and reduces wear on corners.
• Deep sockets reach recessed fasteners and provide confident engagement in tight spots.
• Clear size marks and a dedicated storage case keep tools organized and accessible.

Durable Build for Real-World Use

Built to withstand daily workshop use, these sockets resist corrosion and fatigue thanks to robust construction. The deep drive profile and 6-point geometry work together to deliver steady energy transfer, rather than sudden shocks, helping you maintain control during tough jobs.

Versatile, Compatible, and Easy to Use

Designed for compatibility with both manual and pneumatic impact wrenches, the set covers a wide range of vehicles. It supports many popular brands and models, and its deep sockets are designed to reach behind pulleys and other hard-to-access areas without compromising engagement.

Organization and Warranty

Containment is simple with a compact case that keeps all six sockets neatly organized. Each size is clearly marked for quick selection. Sixcow backs this set with a 30-day money-back guarantee and a 12-month warranty for quality-related issues, underscoring a commitment to reliable performance.
