The Stanley Fatmax 18 Piece 3/8″ Drive Hexagon Socket Set is a comprehensive socket set designed for mechanics and tradespeople requiring reliable fastening solutions. This metric socket set features Maxidrive sockets with knurling for improved grip and handling, whilst the neck-down design enables access in restrictive working environments. The Maxidrive profile maximises contact between the socket and nut, reducing the risk of rounding whilst visible dimensions on each socket allow for quick size identification. The set includes a 120-tooth bi-material ratchet providing fine control in tight spaces, along with a 76mm extension bar and universal joint for enhanced versatility when working at awkward angles. Supplied in a PRO-STACK storage module, this socket set integrates fully with the Stanley Fatmax PRO-STACK system, allowing you to connect multiple cases for a complete mobile tool storage solution. The transparent lid provides instant visibility of contents, whilst the secure fixings ensure your tools remain organised during transport between job sites.
