SPEEDAIRE 21AA60 Air Ratchet 1/4 in NPT 1/4 in Square
Compact air ratchet delivering 20 ft-lb torque at 240 RPM with 1/4 in drive for general-duty fastening
- Air-powered ratchet delivers 20 ft-lb fastening torque
- Free speed of 240 RPM speeds through repetitive bolting tasks

Compact air ratchet for tight fasteners
This SPEEDAIRE air ratchet accepts a 1/4 in square drive and connects through a 1/4 in NPT female inlet. It delivers 20 ft-lb of fastening torque at a free speed of 240 RPM, making it suited for general-duty assembly and maintenance work where space is limited. The ball-detent retainer holds sockets securely during operation.
Air consumption and pressure range
The tool consumes 12 cfm and operates between 50 psi and 90 psi, with a maximum rated pressure of 90 psi. A minimum 3/8 in hose is recommended to maintain adequate flow. Rear exhaust directs air away from the workpiece, helping to keep the work area cleaner during extended use.
Lightweight build with rear exhaust
At 1.1 lb and 6 3/8 in overall length, the ratchet is easy to manoeuvre in confined spaces. The 9/16 in side-to-centre dimension allows access to fasteners close to obstructions. The rear exhaust placement reduces noise directed at the operator and prevents debris from being blown toward the work surface.

Questions about this item
How do I connect the 1/4 in NPT air inlet and what step do people miss?
Use a 3/8 in hose at 90 psi with a 1/4 in NPT male fitting; the step often missed is confirming the compressor delivers 12 cfm at that pressure before first use.
What maintenance or replacement will the 1/4 in square drive ratchet need later?
Lubricate the air motor daily with pneumatic tool oil and inspect the ball-detent retainer for wear; replace the retainer if sockets begin to slip off the 1/4 in drive.
What limit appears first during sustained use at 240 RPM and 20 ft-lb torque?
The 12 cfm air consumption at 90 psi is the first limit; if the compressor cannot maintain that flow, speed and torque drop off during continuous fastening.
