Key Materials & Features:
- Chrome Molybdenum (Cr-Mo) Steel: This is the primary material for impact sockets due to its superior ductility (ability to bend) and toughness, allowing it to deform slightly under impact rather than breaking.
- Thicker Walls: Compared to standard sockets, impact sockets have significantly thicker walls to handle intense force and vibrations from power tools.
- Heat Treatment: The steel is often heat-treated to achieve the optimal balance of hardness and flexibility.
- Black Oxide Coating: A common black finish provides corrosion resistance and durability, making them easy to identify.
- Cross Hole: A hole in the drive end secures them with a retaining pin to an impact wrench, preventing them from falling off.
