Key Features & Benefits
- Sized No.5 for M10–M12 — matched to the thread so the flutes grip the broken fastener without splitting the surrounding metal.
- Reverse spiral flutes — tighten their bite as you turn anticlockwise, backing the broken fastener out cleanly.
- Hardened steel — keeps its edge in rusted and snapped fasteners.
- Square drive end — turn it with a tap wrench or spanner for controlled torque.
- Part of the Geiger No.1–No.5 range — pick the size to match the broken thread from the table below.
When to Use This Extractor
Use the Geiger No.5 (GSESM10-12) when a M10–M12 fastener has snapped or stripped. Centre-punch, drill a pilot hole down the broken fastener, drive the extractor in and back it out anticlockwise. Match the extractor number to the broken thread using the range table.
Pro Tip: Let penetrating oil soak a seized stud before you start, and keep the pilot drill perfectly centred — an off-centre hole weakens one side of the broken fastener and the extractor will spin instead of grip.
