23-Series Heavy-Duty Staples vs. Brass Fasteners
Comparing 2 standards across 14 specifications. 14 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.
Brass Fasteners (also known as Paper Brads or Split Pins) are malleable metal binding pins featuring a round domed head and two flexible flat prongs. Sized from 0.5 inches (13 mm) to 2.0 inches (51 mm), they are passed through punched holes and spread flat against the back of the document, serving as the industry standard for Hollywood film screenplay binding.
