Stahlwille Ring Insert Tools

Stahlwille ring insert tools are designed for secure, full-contact engagement around fasteners, making them ideal for high-precision torque applications where slippage is not an option. Compatible with MANOSKOP® and other torque wrench systems, these inserts feature a robust design, offset or straight profiles, and are available in multiple sizes and drive interfaces (e.g., 9x12 mm, 14x18 mm). Manufactured in Germany to DIN/ISO standards, Stahlwille ring inserts provide reliable, repeatable torque delivery for aerospace, automotive, and heavy machinery industries. Perfect for fasteners in recessed or limited-clearance areas.
