Heavy-Duty 1-Inch Drive Socket

Professional Fleet and Industrial Use

This socket suits technicians servicing heavy-duty vehicles and industrial equipment where a 1-inch drive and deep well are required. It is not intended for light automotive tasks, smaller drive platforms, or general-purpose toolkits.

Questions about this item

What comes in the box and do I need to buy a 1-inch drive ratchet or extension separately?

The socket is sold individually; a 1-inch drive ratchet, air wrench, adapter or extension is required and not included.

Which size should I choose for heavy-duty wheel nuts on large trucks?

The 1-1/2 inch 6-point deep well fits extended threads and recessed bolts on trucks, tractors and construction equipment.

What does the 150% ASME torque rating mean when the socket is on an impact gun?

It is rated to withstand 150% of the ASME torque standard, so it handles the high output of 1-inch drive impact tools without cracking.
