Sk 33320 Impact Socket 3/8 in Drive 5/8 in 6-point

Product Description

The SK 33320 is a 6-point impact socket designed for heavy-duty fastening and removal applications in trade and industrial environments. Built on a 3/8 inch drive, it accepts a 5/8 inch (0.625 inch) fastener and measures 2-21/64 inches overall length. The 6-point geometry delivers full surface contact on fastener flats, reducing the risk of rounding under high torque. Mechanics, millwrights, HVAC technicians, and plumbers rely on this socket type for both air and electric impact wrench applications where standard chrome sockets are not rated for the task.

This socket suits residential and light commercial service work wherever a 3/8 inch drive impact tool is the preferred choice. Typical applications include equipment installation, mechanical fastening, and maintenance tasks that call for a compact, durable 5/8 inch socket. The universal style designation indicates broad general-purpose suitability across common fastener types encountered in field and shop environments.

Key Features

• 6-point design provides full flat-to-flat contact, reducing fastener rounding under impact loads

Compatibility

Designed as an OEM-style impact socket for use with 3/8 inch drive impact wrenches, ratchets, and extension bars rated for impact service.

Installation Notes

Impact sockets must only be used with impact-rated drive tools — never substitute chrome hand-tool sockets in impact applications. Inspect the socket for cracks or deformation before each use and retire any damaged socket immediately. Ensure the socket is fully seated on the drive anvil and the fastener before applying torque.
