Designed specifically for heavy-duty industrial scenarios, these sockets feature thickened hexagonal walls (30% thicker than standard models), capable of withstanding up to 300N・m of torque—ideal for tasks like removing bolts in mining machinery. They are compatible with high-power equipment such as large pneumatic wrenches and hydraulic tools. The internal tooth pattern undergoes special strengthening, increasing the 咬合 area (contact area) with bolt heads by 40%. This ensures effective power transmission even for severely rusted or deformed bolts (e.g., long-exposed components in outdoor infrastructure), preventing slippage or tooth breakage.
The tail drive interface adopts an explosion-proof round shoulder structure. When overloaded torque is applied, stress is preferentially dispersed through the round shoulder rather than concentrated on the interface edge, reducing the risk of fracture. Some models are equipped with anti-detachment locking rings that automatically secure onto bolts, combined with a non-slip knurled outer surface (0.8mm groove depth) for stable grip even when wearing protective gloves. This eliminates the risk of tool drops during overhead work.
Available in sizes ranging from 10mm to 50mm (including custom non-standard sizes), they come in three lengths: 15cm (standard), 25cm (deep hole), and 40cm (extra-long). These can be paired with heavy-duty extension rods to reach deep into large equipment cavities (e.g., shield machine gearboxes). They are suitable for wind power equipment maintenance, heavy truck engine repair, port machinery assembly, and other scenarios, particularly for production lines requiring frequent disassembly and assembly of high-strength bolts.
Sold in 8-12 piece heavy-duty sets, they include common large-sized sockets and adapters (e.g., 3/4" square head to 1" drive interface), packaged in drop-resistant engineering plastic storage cases (50kg load-bearing capacity).
