Sioux 5000A 1/2" Drive Loosen Only Impact Wrench

Engineered specifically for tyre fitment centres, wheel service bays, and automotive workshops that need to eliminate the risk of over-tightened wheel nuts without sacrificing the speed and efficiency of pneumatic impact wrench operation, the Sioux 5000A 1/2" Drive Loosen Only Impact Wrench delivers full pneumatic impact performance in the loosening direction only — making it physically impossible to use the tool to tighten wheel nuts, and therefore physically impossible to over-torque wheel studs, crack alloy wheel seats, or distort brake discs through impact wrench over-tightening.

• Loosen only operation is the defining feature of the Sioux 5000A — the tool physically cannot be used to tighten fasteners, making it the only safe pneumatic impact wrench for wheel nut removal in a professional fitment centre environment where over-tightening is a persistent risk.
• Eliminates over-tightening of lug nuts — the single most common cause of alloy wheel cracking, brake disc distortion, wheel stud stretching, and thread stripping in fitment centres — by removing the tightening function from the loosening tool entirely, rather than relying on operator discipline or torque limiting features that can be bypassed.
• Pneumatic operation delivers the fast, high-torque loosening performance required to break seized, corroded, and over-torqued wheel nuts quickly and efficiently, maintaining the speed advantage of impact wrench operation without the over-tightening risk.
• 1/2" square drive is compatible with the full range of standard 1/2" drive impact sockets, lug nut sockets, and adaptor sets — making the 5000A immediately usable with existing workshop socket inventory.
• Professional Sioux build quality delivers the durability and consistent performance required for continuous daily use in high-volume fitment centre wheel removal operations, backed by the engineering reputation of the Sioux brand.
• Reduces workshop liability and warranty claims by eliminating a category of preventable wheel fastener damage at source — protecting the workshop's reputation and reducing the cost of rectifying over-tightening damage on customer vehicles.
• Complements the IR070441-0N-WO Torque Wrench (Tighten Only) — together the Sioux 5000A and Irimo torque wrench provide a complete, safe wheel removal and installation workflow: loosen with the Sioux impact wrench, tighten to the correct torque with the Irimo torque wrench, and never use an impact wrench to tighten a wheel nut.
• Compatible with the 5000A-REV-WO reverse only companion tool for workshops that prefer a dedicated reverse-only variant in addition to the standard loosen-only 5000A.
