3/4 in Drive Deep Impact Socket
This 3/4 in drive deep impact socket fits 1 7/16 in SAE fasteners with a six-point opening. It is made from nickel aluminum bronze, a non-sparking alloy suited for hazardous environments. The tool meets ASTM A342 and carries FM Approval for safety compliance. Professional mechanics and industrial maintenance crews use it where spark risk must be eliminated.
Non-sparking alloy and deep reach
The nickel aluminum bronze construction prevents ignition in flammable atmospheres while resisting corrosion. An unfinished surface avoids plating that could chip under heavy impact loads. The deep well engages long bolt threads and recessed nuts without an extension. A 3/4 in square drive matches standard impact guns and breaker bars.
SAE sizing and single-hex limitation
The socket covers only the 1 7/16 in SAE size, so additional sockets are needed for other bolt diameters. The six-point profile grips standard hex heads but cannot engage twelve-point or spline fasteners. Users requiring metric sizes or different drive standards must select separate tools.

Questions about this item
What drive standard does the 3/4 in drive socket follow, and what torque limit does that cap in practice?
The socket uses a 3/4 in square drive to ASTM A342, which defines the dimensional standard that limits practical torque to the drive's rated capacity.
What physical clearance does the 1 7/16 in deep socket need to fit over a fastener?
The deep 6-point socket fits a 1 7/16 in SAE fastener and requires enough bolt protrusion to engage the full broach depth.
How is this impact socket installed, and what step do people often miss?
Seat the 6-point broach fully on the fastener before applying impact force; skipping full engagement rounds the corners.
