Air ratchet: lower torque (typical 35-110 Nm), controllable rotation speed, does not produce the impulsive impact action of an impact wrench. Best for fasteners that need to be tightened to specific torque (where impact wrenches over-tighten), brass-and-bronze fasteners (which strip under impact), threaded components in delicate housings, and general workshop tasks where the impulse action of an impact wrench would damage the work. Air impact wrench: higher torque (typical 200-1,500+ Nm), impulsive impact action breaks loose seized fasteners. Better for heavy-duty fastener removal.

Match the drive size to the fastener range: 1/4″ drive — small fasteners (M3-M6 metric, #4-#10 UNC), ignition and electrical components, accessory fitments. 3/8″ drive — general workshop and automotive fastener work (M5-M10), the trade workshop standard. 1/2″ drive — heavier fasteners (M8-M16), suspension and engine components, plant-equipment service. Most trade workshops have all three sizes for different jobs. The drive size determines the socket compatibility — 3/8″ drive sockets fit on 3/8″ drive ratchets only.

Match the rated maximum torque to the largest fastener you'll regularly use. For automotive service: 3/8″ drive air ratchets at 70-110 Nm cover most fasteners (the typical M10 fastener torque range). For plant-equipment service: 1/2″ drive air ratchets at 130-200+ Nm cover most service fasteners. The air ratchet's rated torque is the maximum applied — for tightening, finish with a torque wrench to the manufacturer's specification rather than relying on the ratchet alone. The torque rating is on every product page.

Yes. Matched impact-rated socket sets (impact-rated sockets are stronger than chrome sockets — required for any air-tool socket use; chrome sockets can fail under impact and air-tool action), matched extension bars, swivel adapters and universal joints (for restricted-access work), and reducer and adapter kits (for using sockets across drive sizes — e.g., 1/2″ drive ratchet driving 3/8″ drive sockets) are available across the air-tool accessory range. Always specify impact-rated for air-tool use.

Every product is backed by our Fit Guarantee. If a part is incompatible with your machine, you can return it hassle-free. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will arrange collection. For other returns, email us first to obtain a Return Merchandise Number before sending. Returns are accepted within 30 days of purchase, in original packaging, on UK orders. A restocking fee may apply on returns where the buyer has changed their mind. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and "Check where we deliver" confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.

Air Ratchet Wrenches

FilterFilters
View as Grid List

Within Compressors > Air Tools, Air Ratchet Wrenches covers the pneumatic ratchet-pattern fastener tools used in automotive service, plant-equipment service, fabrication, and the wider trade and industrial workshop applications — covering 1/4″ drive air ratchets (small-fastener work, ignition components, accessory fitments), 3/8″ drive air ratchets (the trade workshop standard size for general fastener work), 1/2″ drive air ratchets (heavier-duty fastener applications), and the matching socket sets and accessory hardware.

Parts for Machines supplies air ratchet wrenches across the trade and industrial ranges. Air-powered ratchet wrenches give the speed of an air tool combined with the controllable torque of a manual ratchet — useful for fastener removal where impact wrenches would be too aggressive (delicate fasteners, threaded components, brass-and-bronze parts) but where manual ratchet would be too slow.

We are an authorised distributor and seller of SIP, Nuair, and Sealey across the air ratchet wrench range. SIP covers the broadest selection — 1/4″, 3/8″, and 1/2″ drive air ratchets with various torque capabilities. Nuair extends the range with workshop and contractor variants. Sealey covers trade-grade air ratchet wrenches with specific torque ratings for automotive service.

Product pages list the drive size (1/4″, 3/8″, 1/2″), the rated maximum torque (in Nm — typical 35-110 Nm for 3/8″ drive air ratchets; higher for 1/2″ drives), the rated free speed (typical 150-300 RPM for ratchet operation), the rated air consumption (typical 3-5 CFM at 90psi), the recommended air pressure, the air inlet thread, the head height (the depth of the ratchet head — important for restricted-access work), the rotation direction (forward, reverse, or selectable), the body weight, and the noise/vibration ratings. Trade pricing on bulk and contractor orders is available; contact the team via WhatsApp 07754288583.
