The SGS Mechanics Expansion Kit is a targeted upgrade package designed to expand fastener capability, improve access, and enhance workflow efficiency in any professional or enthusiast workshop. Built around five premium foam‑insert fastener sets, this expansion kit adds essential coverage for external star fasteners, deep impact applications, drive conversions, extended reach, and high‑access ratcheting.
Whether paired with an existing SGS tool bundle or used to strengthen a custom workshop setup, the STKFS04 delivers immediate improvements in versatility, organisation, and day‑to‑day mechanical performance.
Features and Benefits
Expanded Fastener Coverage: Adds external star sockets, deep impact sockets, and full drive‑conversion capability — ideal for modern automotive platforms, suspension work, and stubborn fasteners.
High‑Access Flex‑Head Spanners: The 12‑piece flex ratchet spanner set provides fast, repeatable fastening in tight or obstructed spaces, improving speed and efficiency across engine bays and interior work.
Extended Reach & Access: The 9‑piece extension bar set covers 1/4", 3/8", and 1/2" drives, enabling deeper access into recessed fasteners, wheel arches, and engine compartments.
Drawer‑Ready Organisation: All sets are supplied in high‑density EVA foam inserts, creating a clean, instantly organised layout in SGS Pro‑range toolchest drawers.
Ideal Modular Upgrade: Designed as a perfect expansion for existing SGS mechanic bundles, adding capability without duplication.
