Professional Heavy-Duty Impact Socket

The Steelman 79318 is a 46 mm 6-point impact socket built for a 3/4-inch drive. It is made from drop-forged, heat-treated chromoly steel with a black phosphate coating and laser-etched size markings. A ball detent recess secures the socket to ratchets, air wrenches, adapters and extensions.

Technicians Servicing Large Equipment

This socket suits mechanics working on large trucks, tractor trailers, farming equipment, oilfield machinery, construction gear and mass transit vehicles. It is rated to withstand 150% of ASME torque requirements for impact tools. Buyers who need a different drive size or metric opening should look at other options.

46 mm 6-Point Opening

The single specification that decides fit is the 46 mm 6-point hex opening combined with the 3/4-inch drive. The 6-point design grips fastener flats rather than corners to reduce rounding. Verify the fastener size and drive requirement before purchase.

Questions about this item

What does the 46 mm size mean when I use this socket on a heavy-duty fastener?

The 46 mm opening fits nuts and bolts with a 46 mm across-flats dimension, common on large trucks, tractors and construction equipment.

How does the 3/4-inch drive and ball detent work with my impact wrench?

The 3/4-inch square drive with ball detent recess locks onto ratchets, air wrenches, adapters and extensions so the socket stays secure under impact loads.

What clearance do I need to fit this socket onto a bolt head?

The 6-point design grips the flat sides of the fastener, reducing corner rounding while requiring standard hex clearance for the 46 mm size.
