Description
Overview:
The Sealey SA4 is a heavy‐duty air impact wrench with a 3/4 inch (19.05 mm) square drive, built for high-torque fastening and loosening on larger fasteners. It features a polished aluminium housing with a textured, comfortable grip to help reduce hand fatigue during longer jobs. A rocking‐dog hammer mechanism drives a hardened anvil and cage for long service life under tough use. Designed for workshop airlines, it is suited to automotive, commercial vehicle, plant and agricultural maintenance where reliable, repeatable performance matters. With reversible action and four-position adjustable air/torque control, the SA4 gives practical control over power delivery, helping protect threads and components while speeding up wheel, suspension, chassis and general repair tasks.
