The Bahco S4RM/3T is a professional-grade reversible ratchet ring spanner set designed for efficient fastening work in confined spaces. This 3-piece set covers 12 metric sizes from 8mm to 19mm, making it a versatile addition to any mechanic's or tradesperson's toolkit. Manufactured from top-quality forged steel with a nickel and chrome-plated matt finish, these ratcheting spanners deliver both durability and a smooth, secure grip during operation. Each spanner features four sized ring headstwo at each endallowing you to select the appropriate size without swapping tools. The reversible ratchet mechanism is operated by a simple direction lever, enabling you to tighten or loosen nuts and bolts with minimal angular movement. This makes the set particularly valuable for motor mechanics and maintenance engineers working in awkward or restricted areas where conventional spanners would require excessive swing clearance. The set comprises three double-ended spanners covering 8 x 9 x 10 x 11m
