24/6 European Staple

Direct Answer

The 24/6 staple (standardized under DIN 7405) is the primary European office stapler standard, featuring a 24-gauge wire (approx. 0.51 mm diameter) with a 6 mm leg length and 12.7 mm crown width. Utilizing thicker steel wire than 26/6, it provides superior column strength to penetrate dense, high-grammage coated paper without leg buckling.

Why 24/6 Resists Staple Jamming

When stapling through glossy, heavy coated brochure paper (120 gsm+) or cardstock, the thinner wire of a 26/6 staple can buckle under compression against the stapler anvil. The heavier 24 AWG wire of a 24/6 staple resists column buckling, ensuring crisp clinch closure through dense materials.
