The Crescent CDS81N is a professional-grade 21 mm metric socket designed for high-performance use in automotive, industrial, and mechanical applications. With a 12-point configuration and 1/2-inch drive, this socket delivers strength, precision, and durability for demanding tasks.

Key Features:

• Crestoloy® Chrome Alloy Steel Construction
  Forged from Crestoloy® alloy steel, this socket is engineered for superior strength and long-lasting durability. It is heat-treated to withstand high torque and resist wear in tough environments.

• 12-Point Design for Versatile Engagement
  The 12-point socket geometry allows for easier alignment with fasteners and provides more engagement angles, especially useful in tight or awkward spaces.

• Off-Corner Loading Technology
  Crescent’s off-corner loading design reduces fastener rounding by applying torque to the flat sides of the fastener rather than the corners, extending the life of both the socket and the fastener.

• Nickel Chrome Plated Finish
  The mirror-polished chrome finish resists corrosion and is easy to clean, maintaining a professional appearance and ensuring long-term performance.

• Clearly Stamped Size Markings
  The socket features deeply stamped, high-contrast size markings for quick identification, even in low-light or greasy conditions.

• Standard Length Format
  With an overall length of approximately 1.5 inches, this socket offers a balance of reach and control, making it suitable for a wide range of applications.
