sixcow 22mm Harmonic Balancer Socket 1/2" Drive — Weighted Deep 6-Point Impact Socket for Crank Bolts

The sixcow 77110 22mm harmonic balancer socket is a heavy-duty, impact-ready 1/2" drive socket engineered to remove 22mm crankshaft and pulley damper bolts with three times the momentum of a standard impact socket.

This socket is designed for professional mechanics and DIYers working on a wide range of vehicle makes — including Toyota, Ford, Dodge, Jeep, Kia, Lexus, Isuzu, GM, BMW and more — that use a 22 mm hex crank or pulley damper bolt. Built from heat-treated 40Cr alloy steel and CNC-machined to precise tolerances, the tool combines a deep, 6-point profile with reinforced walls to transfer high torque cleanly, reduce slippage and resist deformation under impact use. It ships in a sturdy blow-mold case and is marked for quick size identification.

How does this socket deliver more torque than a standard impact socket?

The 77110 is engineered with optimized depth and increased wall thickness so impact energy is directed into the fastener instead of flexing the socket. Its mass distribution and internal profile increase momentum and enable up to three times the effective torque compared with many conventional impact sockets.

• Reinforced walls focus impact force to the bolt.
• Weighted design increases momentum for stubborn bolts.
• Deep 1/2" drive seating for strong tool engagement.
• Heat-treated 40Cr steel maintains strength under repeated use.

Will this fit my vehicle’s crank bolt or pulley damper?

This socket fits any application that uses a 22 mm hex crank or harmonic balancer bolt. The listing corresponds to OE part style 77110 and is compatible across many manufacturers and engine families where a 22mm hex is specified.

• Works with Toyota, Lexus, Kia, Isuzu, Ford, Dodge, Jeep, GM and more.
• For 22 mm hex pulley damper or crank bolt applications.
• Use with 1/2" drive impact wrenches, breakers, or torque tools.

How does the 6-point design protect fasteners and tools?

The 6-point interior offers a larger contact area on hex surfaces, which minimizes rounding and spreads load evenly across the bolt faces. That prevents slippage during high-torque impact removal and reduces wear on both the socket and fastener heads.

• Curved interior profile ensures positive engagement on hex bolts.
• Reduced risk of bolt rounding during high-torque removal.
• Stronger grip with less localized stress on bolt corners.

What materials and build features ensure long service life?

The socket is CNC-machined from drop-forged 40Cr alloy steel and then heat-treated for impact strength and corrosion resistance. A clear, laser-style size mark and included blow-mold case make storage and identification simple between jobs.

• Drop-forged, heat-treated 40Cr alloy steel construction.
• Precision CNC machining for exact hex fit and depth control.
• Sturdy blow-mold case for transport and organized storage.

Who this is for: The sixcow 22mm harmonic balancer socket is ideal for professional mechanics, home garages, fleet technicians and enthusiasts who need a dependable, impact-rated 1/2" drive solution for tight crankshaft or pulley damper bolts. If you frequently work on Japanese, American or European engines that use a 22mm hex fastener and want a socket that reduces slippage, resists wear and delivers higher effective torque, this tool is built for you. Every purchase is backed by a 30-day money-back guarantee and a 12-month warranty on quality-related issues for added confidence.
