Impact Socket Proline 18470, 78 mm height, model 18470

Proline impact socket model 18470 is an impact-rated socket designed for professional mechanic and workshop use. Manufactured from chromium-molybdenum steel and heat-treated for impact work, this 78 mm height socket is intended to withstand repeated high-torque loads from pneumatic and electric impact wrenches. The socket's construction focuses on durability and resistance to deformation under shock loading while maintaining accurate fit to fasteners.

Advantages

The chromium-molybdenum steel construction and heat treatment provide enhanced toughness and fatigue resistance compared with standard tool steels. The 78 mm height offers greater reach for recessed nuts and bolts while preserving sidewall strength. The socket is shaped and finished to ensure secure seating on fastener heads and reliable transfer of impact torque with minimal rounding. Designed specifically for impact tools, it reduces the risk of cracking or chipping under repeated use.

Suitable for

• Automotive repair and maintenance where impact wrenches are used
• Industrial and fleet workshop applications with high-torque fasteners
• Mechanical assembly and disassembly of recessed or deep-set nuts and bolts
• Professional technicians requiring impact-rated hand tool accessories

Key specifications

• Material: chromium-molybdenum steel (impact-grade)
• Height: 78 mm
• Design: impact socket for use with impact wrenches
• Finish: industrial protective finish for corrosion resistance and wear
• Intended use: pneumatic and electric impact tools; high-torque applications

How to use

Select the correct socket size for the fastener and attach it securely to a compatible impact wrench or adapter. Ensure the socket fully engages the fastener head before applying torque. Operate the impact tool according to the tool manufacturer's instructions and apply torque incrementally when possible to avoid sudden overstress. After use, inspect the socket for cracks, deformation or excessive wear and store in a dry, organized tool location.

Usage recommendations

Use only with impact-rated adapters and drive tools; do not use impact sockets with hand ratchets or non-impact tools for tasks requiring fine torque control. Regularly inspect the socket for damage and replace if any deformation or cracking is detected to maintain safe operation.
