23-Series Heavy-Duty Staples vs. Prong Paper Fasteners
Comparing 2 standards across 12 specifications. 12 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.
Two-Prong Metal Paper Fasteners (standardized with a 2.75-inch / 69.85 mm center-to-center prong spacing) are heavy-gauge tin-plated steel compressors used with self-adhesive prong bases inside classification folders, legal case files, and medical patient charts to secure up to 500 hole-punched sheets.
