Counters hire impact wrenches by drive size, and the drive follows the fastener rather than the brand. A half inch gun handles wheel nuts, deck bolts and most vehicle work at roughly $25 to $45 a day; a three quarter or one inch gun for structural bolts and heavy plant runs nearer $55 to $95. Cordless units cost more to hire than air guns and need no compressor.
Drive size, not horsepower, picks the gun
Sockets match a square drive, so the drive decides which sockets fit and roughly what torque the tool makes. Half inch covers wheel nuts and general assembly. Three quarter and one inch belong on structural steel, trailer hubs and machinery. Renting one size up and fitting an adaptor is how sockets crack, so take the right drive from the start.
A pneumatic gun is only half the order
An air impact needs a compressor that holds volume, not just pressure, plus hose and a lubricator. A half inch gun wants a few cubic feet a minute continuously and a larger one considerably more, so the small pancake unit in the garage stalls after two nuts. Yards will quote gun and compressor together if you ask for both.
Cordless has changed what the counter stocks
Battery impacts now cover most work a half inch air gun used to do, and they arrive as a kit with two batteries and a charger. They cost more per day and run time limits a long session, but there is no hose, no compressor and no fuel. For an afternoon of wheel or deck work the kit is usually cheaper overall.
Breaking a joint and setting it are different jobs
An impact is a loosening tool. It will run a fastener down quickly, but the figure it applies is not controlled, and anything with a specification wants a torque wrench for the final setting. Hire the impact to break the joint and a torque wrench to finish it, which most counters stock side by side.
Questions people ask about rent impact wrench
What size impact wrench for lug nuts?
A half inch drive covers cars, light trucks and most trailers. Heavy truck wheels want a three quarter or one inch gun. Whatever the tool, set the nuts with a torque wrench afterwards rather than trusting whatever the impact happened to apply.
Do impact sockets come with the hire?
Not always. Impact rated sockets are usually a separate line, and ordinary chrome sockets shatter on a gun. Ask for the impact set in the drive size you booked, and check the sizes actually cover the fastener in front of you.
How big a compressor does an air impact need?
Enough volume to keep up rather than a high pressure rating. A half inch gun typically wants a unit rated a few cubic feet a minute at ninety pounds with a tank behind it; heavier guns want considerably more. Give the counter the gun model and it will match a compressor.
