23-Series Heavy-Duty Staples vs. Paper Clips
Comparing 2 standards across 13 specifications. 13 key differences identified.
The 23-Series staple family (standardized under DIN 7405) uses ultra-stout 23-gauge high-tensile steel wire (approx. 0.57 mm diameter) with a 12.8 mm crown and graduated leg lengths from 8 mm (23/8 for 50 sheets) up to 24 mm (23/24 for 210+ sheets). It is the industrial standard for legal briefs, financial prospectuses, and thick catalog binding.
The Gem Paper Clip (introduced by The Gem Manufacturing Company in the 1890s) is a single looped piece of galvanized spring-steel wire that binds loose sheets using torsional elastic deflection. Available in standard No. 1 (33 mm / 1.3 in) and Jumbo (50 mm / 2.0 in) sizes, alongside specialized Butterfly/Trefoil wire clamps for thick 50-sheet reports.
