Designed specifically for heavy-duty industries, these sockets feature a hexagonal wall structure thickened by 30%, capable of withstanding a maximum torque of 300N·m—ideal for tasks like removing bolts in mining machinery or bridge infrastructure. They are compatible with high-load equipment such as large pneumatic wrenches and hydraulic tools.

The tail adopts an explosion-proof round shoulder structure. When torque is overloaded, the round shoulder dissipates stress through deformation, preventing direct fracture of the interface. Tested to withstand 1.5 times the rated torque without damage, this design ensures exceptional durability under extreme loads.

Sold in 8-12 piece sets, they include common large-sized sockets and a 3/4" to 1" drive adapter for compatibility with multiple power tools. The accompanying drop-resistant engineering plastic case features anti-collision EVA lining, supports a 50kg load, and is both waterproof and dustproof—perfect for field operations or frequent handling on production lines. The unique self-cleaning tooth pattern design quickly expels iron filings and oil, reducing downtime for maintenance and increasing continuous operation efficiency by 20%.

With core advantages of "high strength, long lifespan, and high safety," heavy-duty metric hexagon drive sockets are essential tools for heavy industries such as metallurgy, energy, and transportation, particularly in harsh scenarios requiring 24-hour continuous operation.
