For OO and N Gauge
Blackened mild steel pins, 14mm (9/16") long. For fixing most Streamline track gauges to wood fibre board (Sundeala) or similar baseboard surfaces.
Note that these are fine pins, not nails and cannot be driven with a hammer. We recommend drilling through sleepers with a 0.5 or 0.7mm drill. When using plywood or chipboard continuing drilling into the board to get the pin started. The pin can normally be driven home with pliers or a small hammer.
