Precise SAE Fit
The Grey Pneumatic 4038R is a 1" drive socket sized at 1-3/16" SAE with a six-point profile. It is built for technicians who need a single, accurately sized impact socket for heavy-duty fastening tasks.
1" Drive Compatibility
The square drive measures exactly one inch, so the socket only fits ratchets, breakers or impact guns with a matching 1" drive. It will not engage smaller 3/4" or 1/2" drives, nor will it accept larger drive sizes.
Impact-Rated Construction
The black oxide finish and six-point geometry distribute torque across the fastener flats, reducing rounding during high-torque impacts. The thick-wall design absorbs repeated hammer blows without cracking or deforming under normal shop use.

Questions about this item
What does the 1-3/16 inch size mean when I put this socket on a 1 inch drive tool?
The 1-3/16 inch marking is the fastener size this six-point socket fits; the 1 inch drive hole matches your impact gun or breaker bar so the tool turns the socket without an adapter.
How does the 1 inch drive standard limit what I can use with this socket?
A 1 inch square drive only accepts 1 inch drive ratchets, extensions and impact guns; smaller 3/4 inch or 1/2 inch tools will not engage without a step-up adapter that adds length and potential weakness.
What clearance and retention does the 6-point black impact socket need to mount securely?
The six-point opening grips the fastener flats, the black oxide finish resists corrosion, and the 1 inch drive square has a retaining pin groove so the socket locks onto your impact gun anvil.
