Tackle high-torque, multi-spline fasteners with this US PRO Industrial 9-piece impact spline bit socket set. Each socket uses a Chrome Vanadium (CR-V) body paired with a precision S2 tool-steel bit for strength, shock resistance and long life under impact use. The 3/8" drive keeps the footprint small for under-bonnet and interior access, while the 48 mm overall length gives you room to work with compact ratchets or cordless impact drivers set to an appropriate (low) power level. Finished in phosphate for added corrosion protection—ideal for automotive, plant and general maintenance.
