Sk 33318 Impact Socket 3/8 in Drive 9/16 in 6-point

Product Description

The SK 33318 is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. It accepts a 9/16 inch (0.563 inch decimal) fastener and measures 2-7/32 inches overall length, making it suitable for moderately deep fastener access without requiring a dedicated deep socket. The universal style fits standard impact driver setups. At 0.25 pounds, it is lightweight enough for extended overhead or confined-space work. This socket is built for professional-grade torque applications where a standard chrome socket would risk cracking or shattering under repeated impact loads.

The SK 33318 is suited for general mechanical, automotive, HVAC equipment service, and industrial maintenance tasks where 3/8 inch drive impact tools are standard. The 6-point design concentrates drive force on flat fastener faces rather than corners, reducing the chance of rounding off hex-head bolts and nuts. Technicians working on equipment panels, compressor mounts, condenser frames, and structural fasteners will find the overall length appropriate for most standard-depth applications.

Key Features

• 3/8 inch drive compatible with standard impact wrenches and ratchets
• 9/16 inch (0.563 inch) socket size for common hex-head fasteners
• 6-point geometry reduces fastener rounding under impact torque
• Universal style for broad tool compatibility
• 2-7/32 inch overall length for standard-depth fastener access
• Lightweight at 0.25 pounds for reduced fatigue during extended use

Compatibility

Designed for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring a 9/16 inch 6-point socket.

Installation Notes

Impact sockets are intended for use with impact drivers and air or electric impact wrenches only — do not substitute standard chrome hand-tool sockets for impact applications. Inspect the socket for cracks or deformation before each use and replace if any damage is found. Ensure the socket is fully seated on the drive anvil and the fastener before applying torque. No lubrication of the socket drive square is required for standard use.
