The Stanley Fatmax M Stak Socket Set 3/8" – 18 Piece is a compact, high-performance solution built for the serious DIYer or professional. Designed for seamless integration with the Stanley Fatmax PRO-STACK storage system, this set locks securely onto larger PRO-STACK units, creating a truly mobile and secure tool solution. Its transparent lid makes identifying contents quick and easy, saving you time on the job.
At the core of the set is a 120-tooth bi-material ratchet, delivering smooth, precise performance with 3° increments—ideal for tight and awkward spaces where control and accuracy matter. The X-knurl Maxidrive sockets offer excellent grip with knurled exteriors for easy handling, even with oily hands. Their neck-down design and next-gen Maxidrive profile maximise contact with nuts and bolts, reducing the risk of wear and rounding.
Built with compactness in mind, the set makes no compromise on storage space or strength. Accessories like the 3" extension bar and universal joint provide increased reach and flexibility in hard-to-access areas. Whether you're working in a workshop, garage, or onsite, this set delivers rugged performance, efficient organisation, and dependable durability for everyday use.
