Yoursme 19mm Harmonic Balancer Socket (77080) — 1/2" Drive Impact-Ready, High-Mass 6-Point

The Yoursme 19mm harmonic balancer socket (model 77080) is a heavy-duty, 6-point 1/2" drive tool engineered to remove Honda 19mm hex crankshaft pulley/damper bolts quickly and with minimal slipping.

If you work on Honda engines that use a 19mm hex on the crank pulley damper bolt, this specially designed socket streamlines bolt removal while reducing flex and vibration. Built from heat-treated GB 40CR alloy steel and engineered with extra mass, the socket delivers higher torque transfer than ordinary impact sockets. Its 89mm overall length reaches recessed bolts, and the precision 6-point geometry helps avoid rounding the bolt head during removal.

How does this socket make removing stubborn Honda crank bolts easier?

The socket concentrates mass and strength around the bolt interface to deliver more impactful torque with less deformation. Its deep, counter-weighted body reduces flex and absorbs vibration so that turns from your breaker bar or impact gun go into the bolt rather than bending the tool.

• High-mass design for greater torque delivery and energy transfer
• Heat-treated GB 40CR alloy steel for improved durability
• 1/2" square drive compatible with standard breaker bars and impact guns
• Overall length 89mm to reach recessed crank bolts

Will this socket fit my Honda crankshaft pulley bolt?

Yes—this socket is sized for 19mm hex bolts commonly used on many Honda pulleys and harmonic balancers. The socket’s 6-point profile provides an accurate, secure grip to reduce the chance of rounding off bolt corners during removal or installation.

• Precise 6-point contact pattern for snug fit
• Designed specifically for 19mm hex pulley/damper bolts
• Works with other 19mm applications as needed
• Compatible with 1/2" drive tools for broad toolroom use

Is this socket safe to use with impact tools and breaker bars?

The 77080 is manufactured to withstand impact-level forces while limiting flex. Heat treatment plus the thicker, counter-weighted design improve shock resistance and longevity compared with thinner, non-impact sockets.

• Impact-quality GB 40CR alloy steel construction
• Heat-treated for greater wear life than ordinary steel
• Balanced mass reduces vibration transfer to fastener and tool
• Suitable for both manual and impact tool use

How fast can I remove a hex pulley damper bolt with this tool?

With the correct breaker bar or impact gun, removal typically takes just a few seconds for bolts that aren’t corroded or seized. Because the socket’s geometry and mass deliver torque efficiently, you often won’t need additional crankshaft-holding tools for many routine jobs.

• Quick bolt engagement and removal when bolt is accessible
• Reduces need for extra holding fixtures in many cases
• Designed for efficient energy transfer to the bolt
• Length allows reach to recessed fasteners for faster work

Who is this for? The Yoursme 19mm harmonic balancer socket is aimed at professional mechanics, independent technicians, and DIY Honda owners who need a reliable 19mm solution for crank pulley or damper bolts. If you frequently service Hondas or work across a variety of engines that use 19mm hex bolts, this durable, purpose-built socket simplifies removal and reduces the risk of damaging bolts and tools. Backed by a 12-month warranty and customer support, it’s a practical addition to any 1/2" drive tool kit.
