The bahco 34 piece 3 8 drive socket and screwdriver bit set is a comprehensive metric socket set designed for professional mechanics and automotive technicians. This versatile 3 8in drive set combines high performance alloy steel sockets with a selection of screwdriver bits, providing essential tools for general mechanical work and automotive maintenance. The sockets feature bahco's dynamic drive™ profile, which protects against wear and damage by distributing force more effectively around the fastener. Each socket has a matt finish that resists corrosion whilst providing a professional appearance. The set includes a slim quick release ratchet handle for improved access in confined spaces, plus two extension bars 75mm and 150mm and a universal joint to reach awkward fasteners. The inclusion of two spark plug sockets 16mm and 21mm makes this set particularly suitable for engine servicing work, whilst the comprehensive range of 1 4in hex, phillips, and slotted bits extends its versatility to lighter assembly and fastening tasks. A spinner handle with a 2 component grip provides additional control when working with the bit holder. All components are supplied in an oil and temperature resistant polypropylene case that protects the tools and keeps them organised on site or in the workshop.
