Bahco Reversible Ratchet Spanner

The Bahco S4RM 4mm x 7mm Reversible Ratchet Spanner is the smallest in the series, covering four compact sizes: 4mm, 5mm, 6mm, and 7mm. These smaller metric sizes are essential for precision work, electronics, small engine repair, instrumentation, and detailed mechanical assemblies where delicate fasteners require careful handling. Manufactured from top-quality forged steel with nickel and chrome plating in a matt finish, this compact spanner delivers precision and reliability despite its smaller size. The ratcheting mechanism is particularly advantageous when working with small fasteners in tight spaces, such as inside electrical enclosures, small engine compartments, or when assembling intricate mechanical components where finger access is limited. The reversible direction lever allows quick switching between operations, whilst the dual-head design means you're carrying one tool that replaces four traditional spanners, making it perfect for precision work and mobile applications.
