The bahco s877 is a comprehensive 94 piece socket and spanner set combining 1 4in and 1 2in drive sockets with combination spanners, ideal for professional mechanics and engineers requiring a versatile toolkit. This extensive set features bahco's dynamic drive profile technology, designed to reduce fastener rounding and provide improved grip on worn fixings. The set covers a wide range of applications with both metric and imperial sockets, including standard, deep, and impact variants. The 1 4in drive components are suited to precision work on smaller fasteners, whilst the 1 2in drive sockets handle heavier duty tasks. The inclusion of 13 combination spanners from 7mm to 19mm and four flex head spanners provides additional versatility for working in confined spaces. All tools are housed in a robust three component case that offers impact and oil resistance, making it suitable for workshop environments. The case features a removable tool rack specifically designed for the combination spanners, allowing quick access and organised storage. Extension bars, universal joints, a sliding t bar, and reversible ratchets for both drive sizes provide the flexibility needed for tackling awkward fastener positions across automotive, mechanical, and general maintenance applications.
