Product Description

Forged Impact Socket Wrench – Engineered for Extreme Durability
Forged from high-grade chromium-molybdenum steel (e.g., 42CrMo), our impact sockets are heat-treated to achieve exceptional hardness (HRC 45-55) and tensile strength (1,000+ MPa), ensuring resistance to deformation under heavy torque. The precision 6-point or 12-point design minimizes fastener rounding, while a black oxide or electroplated finish enhances corrosion resistance.
Designed for use with pneumatic/impact wrenches, these sockets feature a reinforced wall thickness and ANSI/ISO-compliant drive sizes (1/2", 3/4", 1"). Ideal for automotive, industrial, and heavy machinery applications, they withstand repetitive high-torque impacts (up to 2,500 Nm) without cracking. Rigorous testing guarantees compliance with DIN 3122 and ASME B107.1 standards.
Specification
Application
1. Automotive Repair – Used with torque wrenches to tighten critical fasteners like wheel lug nuts, cylinder head bolts, and suspension components to precise specifications.

2. Industrial Machinery Maintenance – Ensures accurate bolt tension in heavy equipment, conveyor systems, and hydraulic assemblies to prevent failures.

3. Aerospace Assembly – Applies calibrated torque to aircraft engine bolts, landing gear, and structural components for safety compliance.

4. Wind Turbine Construction – Secures massive flange bolts and tower connections to withstand dynamic loads and vibrations.

5. Oil & Gas Pipeline Installation – Tightens high-pressure flange bolts and wellhead equipment to prevent leaks in extreme environments.

(Bonus: Also used in precision manufacturing, shipbuilding, and rail maintenance.)
Note: Always match the socket's torque rating (e.g., 2,000+ Nm for heavy-duty models) to the application.
