The ATC24MMISX-A is a robust, purpose-built 24 mm socket designed for torquing Cummins ISX head and main bolts. Known as a heavy duty headbolt socket, it is the preferred tool for installing or removing heavy-load, high-torque fasteners in Cummins ISX diesel engines. Made to handle the high torque requirements of this engine.
Constructed for durability under extreme loads this socket measures 5″ in length and features 90° angle markings permanently etched for accurate torque and angle tightening procedures. It is compatible with ¾″ drive torque wrenches or impact tools, making it a direct replacement or alternative to Cummins part 3165161 and supersedes 3163484 in many applications.
Whether you're performing head gasket replacement, engine rebuilds, or maintenance where precise bolt torque matters, the ATC24MMISX-A ensures consistent, reliable performance across the demanding environments faced by heavy-duty mechanics.
