SKU CH-V79F-EJHK8

A 1-inch drive, six-point socket with a corrosion-resistant black phosphate finish and laser-etched size markings for clear identification

  • 6-point design grips fastener flats securely
  • Black phosphate finish resists corrosion
  • Laser-etched markings simplify size identification
  • Meets ANSI standards for reliability

1" Drive 6-Point Socket 3-1/8

This 1" drive socket fits 3-1/8" fasteners with a six-point opening. A black phosphate coating resists corrosion during heavy automotive and industrial work. Large laser-etched markings simplify size identification on the job site. The tool meets ANSI standards for dimensional accuracy and strength.

Suits heavy-duty maintenance and assembly

Mechanics and technicians turning large bolts with a 1" drive ratchet or impact gun will find the six-point grip secure. Users who need a different drive size, a different opening profile or a smaller socket for confined spaces should choose another tool.

6-point 3-1/8" opening on 1" drive

The six-point 3-1/8" opening on a 1" square drive is the single specification that determines whether this socket matches the fastener and the drive tool you are using. Verify both dimensions before purchase.

Questions about this item

Does the Dynamic D025389 socket come with any accessories or do I need to buy a 1" drive ratchet separately?

The package contains only the single 6-point socket with a black phosphate finish. A compatible 1" drive ratchet or breaker bar must be purchased separately.

How do I know the Dynamic D025389 3-1/8" socket is the right size for my fastener?

The socket is a single 3-1/8" SAE size with large laser-etched markings for clear identification. Choose it only when the bolt or nut measures exactly 3-1/8 inches.

What does the ANSI-standard 6-point design mean when I put this socket on a stubborn bolt?

The 6-point geometry contacts the flat sides of the fastener rather than the corners, reducing rounding risk and allowing higher torque on a 3-1/8" bolt head.
