II. Core Components & Vehicle Compatibility
The set includes multi-size sockets with specialized profiles, lengths, and vehicle-specific fits for common engine cylinder head bolts:

• Socket Profiles/Sizes: T50 (Mercedes-Benz, T-profile), T55/T60 (BMW, T-profile), M10 (VW older models, M-profile), MP10/RT10 (VW/Audi, 200mm, MP-profile), MP12/RT12 (Land Rover, 200mm, MP-profile), MP11/RT11 (Ford, MP-profile), M13 (Toyota, 78mm, M-profile), M17 (Toyota, 78mm, hollow M-profile), RT13/RT14 (GAC Trumpchi, air-impact ready, compatible with pneumatic tools)

III. Application Scope
Designed for cylinder head maintenance on mainstream automotive brands, supporting:

• Engine overhauls (e.g., head gasket replacement, head surface repair)
• Cylinder head component repairs (valves, camshafts) requiring bolt removal/reinstallation
• Compatible with Mercedes-Benz, BMW, Volkswagen, Audi, Land Rover, Ford, Toyota, GAC Trumpchi, and other listed models

IV. Core Functions
As a dedicated cylinder head toolset, it primarily:

• Profile-Specific Fit: Matches vehicle-specific bolt profiles (T/M/MP/RT) to reduce slippage risk and protect critical head bolts/threads
• High Torque Capacity: CR-MO chrome molybdenum steel construction exceeds standard CR-V strength, supporting high-torque demands (e.g., 100-150N·m) for head bolt installation
• Multi-Scenario Adaptability:
  • 1/2-inch drive compatible with pneumatic tools (efficient bulk operations) and manual torque wrenches (precision control)
  • Length variants (200mm/78mm) address deep/shallow bolt installations across cylinder head designs
  • Air-impact sockets enhance efficiency for overhaul tasks

V. Structural & Material Features

• Materials: Heat-treated CR-MO steel provides superior torsion/wear resistance for high-stress head bolt tasks
• Profile Design: Vehicle-specific profiles (e.g., BMW T55, VW MP10) ensure full tooth engagement for even load distribution
• Drive & Length: 1/2-inch drive supports common torque tools; extended lengths (200mm) reach deep head bolts, shorter lengths (78mm) suit shallow installations
• Storage Design: Foam-lined case with precision cutouts prevents socket damage and enables quick access

VI. Usage Scenarios
Primarily used in repair shop engine bays and brand-specific service centers for:

• Cylinder head removal/reinstallation during head gasket failures
• Head bolt torquing after surface machining or component repairs
• Head component service (valves, camshafts) requiring bolt access

VII. Key Considerations

• Match socket profile/size to vehicle specifications to prevent bolt/thread damage
• Follow engine-specific torque sequences/specifications during installation to avoid head warping or stripped threads
• Ensure full socket engagement with bolts before applying pneumatic/manual torque to prevent slippage
• Clean sockets of oil/debris post-use, dry thoroughly, and return to storage to maintain CR-MO integrity and profile precision
