Dynamic D025055 55mm 1" Drive 6-Point Socket

SKU CH-G2A0-W9F0K

A 55 mm, 1-inch drive 6-point socket with a corrosion-resistant black phosphate finish and laser-etched markings for quick size identification

  • 55 mm socket fits large fasteners precisely
  • 1 inch drive handles heavy torque applications
  • 6 point design grips flats to reduce rounding
  • Black phosphate finish resists corrosion in harsh environments
  • Laser etched markings simplify size identification at a glance

55 mm 1" Drive Socket

The Dynamic D025055 is a 55 mm standard socket with a 1 inch square drive and six-point geometry. It is built for heavy-duty fastening on large bolts and studs found in commercial vehicle, agricultural and industrial maintenance. The black phosphate coating resists corrosion in workshop environments.

Replaces worn 1" drive sockets

This socket replaces a 1 inch drive six-point socket that has rounded corners, damaged plating or illegible markings. The upgrade is worth it when the old tool no longer grips 55 mm fasteners securely or when laser-etched size identification is needed to avoid mixing metric and SAE sockets.

Check drive compatibility and clearance

Verify that your 1 inch drive ratchet, breaker bar or impact gun accepts a standard 6-point socket of this length. Confirm the 55 mm size matches the fastener you intend to turn. Ensure the black phosphate finish is acceptable for your workspace safety requirements.

Questions about this item

What size ratchet or breaker bar does the 1" drive socket fit?

The socket has a 1 inch square drive, so it fits any 1 inch drive ratchet, breaker bar or impact wrench with a matching square.

How do I install the socket onto the drive tool?

Align the 6-point opening with the fastener, push the socket square onto the 1 inch drive until the retaining ball clicks into the socket's detent hole.

Will the black phosphate finish wear off and need re-coating?

The corrosion-resistant black phosphate finish is a surface treatment; it does not require re-coating, but inspect for rounding on the 6-point walls before each use.
