Manufactured from heat-treated GB 40CR alloy steel and finished for impact use, the tool combines a deep, 6-point engagement with a counter-weighted body to deliver higher effective torque when used with a 1\/2\" drive impact wrench. It eliminates the need to manually hold the crankshaft during removal and is built to resist rounding and breakage under high load.\n\n\u003ch3\u003eHow does this socket make removing the harmonic balancer bolt easier?\u003c\/h3\u003e\n\u003cp\u003eThe Sunluway 24mm harmonic balancer socket fits the crank bolt head precisely and transfers impact energy efficiently to the bolt, reducing slippage. Its deep profile fully captures the bolt, while the counter-weighted design channels momentum for stronger rotational force.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDeep 6-point contact reduces rounding and improves bite on the bolt head\u003c\/li\u003e\n  \u003cli\u003eCounter-weighted body increases delivered momentum versus standard sockets\u003c\/li\u003e\n  \u003cli\u003eMade for use with 1\/2\" drive impact wrenches—no crank holding required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes this 24mm socket durable enough for impact use?\u003c\/h3\u003e\n\u003cp\u003eThe 77070 socket is forged from heat-treated GB 40CR alloy steel and finished for impact resistance.
