Heavy-Duty 1-Inch Drive Socket

The Steelman 79388 is a 1-inch drive, 1-1/2 inch 6-point deep impact socket built for professional mechanics. It is designed for maintenance and repair on large trucks, tractor trailers, farming equipment, and construction machinery.

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.

ASME Torque Rating and Chromoly Construction

The socket withstands up to 150% of ASME torque specifications thanks to drop-forged, heat-treated chromoly steel. A black phosphate coating resists rust and corrosion while laser-etched markings provide clear size identification.

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.
