Atlas Copco Ltd 28R8F-RR Straight Inline Pneumatic Nutrunner

Atlas Copco LTD28 R8F-RR Straight Inline Pneumatic Nutrunner is a compact tool for precise, controlled tightening of small fasteners in automated and manual assembly cells. It delivers 3-8 Nm of torque at up to 1100 rpm, with a straight inline drive that keeps the operator’s wrist aligned during use. The unit uses a 3/8 in square drive (output size 3/8 in) and is configured for M6 bolts, with a 20 mm center-to-center distance between drive and workpiece. It weighs 2.6 lb and measures 294 mm in length, making it a lightweight option for high-repetition tasks. At free speed it draws about 17 cfm of air and is designed with reversible operation and a shut-off feature for consistent torque control. Hose sizing guidance is 10-13 mm, and the tool is compatible with Atlas Copco LTD mounting plates and reaction-bar fixtures for fixture-based assembly. Originating from Sweden, the LTD straight nutrunner family emphasizes reliable performance in repetitive tightening applications and can be integrated into fixed-fixture or handheld workflows depending on the work cell needs.
