The Bosch PRO 3 Piece Impact Nutsetter Set Imperial is a professional-grade accessory set designed for tightening hex screws, nuts, and bolts with an impact driver or drill driver. Constructed from heat-treated modified steel, each nutsetter delivers the strength and torque resistance needed for heavy-duty fastening applications. A dedicated torsion zone within the design absorbs torque stress, reducing the risk of breakage under demanding conditions. Supplied in three imperial sizes — 1/4", 5/16", and 3/8" — this set is well suited to installers and contractors who regularly work with imperial fixings. Clear laser markings on each piece make identification quick and easy, even when working from a cluttered toolbox.
