Wuxi, Jiangsu Oct 23, 2026 (Issuewire.com) - Large flange blind rivets, also named big head pop rivets, are a special type of single-sided fastening fastener with an extra-wide, oversized flange head compared to regular dome head blind rivets. The enlarged flange provides a much larger load-bearing area to disperse clamping pressure, effectively avoiding pull-through, cracking or deformation when joining thin, soft or brittle materials like plastic, plywood and ultra-thin metal sheets.
1. What Are Large Flange Blind Rivets?1.1 Difference Between Standard Blind Rivets VS Large Flange Blind RivetsThe most difference is flange diameter,We can take diameter 3.2/4/4.8 mm blind rivets for example.You can our difference data .1.2 What Does “Large Flange” Mean for Rivet Bearing Surface
Large flanges expand this bearing surface. The broad flat head spreads clamping force across a far wider zone instead of concentrating pressure right at the hole edge.
2. Main Structure & Working Principle of Large Flange Blind Rivets2.1 Main Components: Rivet Body, Oversized Flange Head, Mandrel
It is made of rivet body ,large flange and mandrel.
2.2 One-Side Installation Process of Large Flange Blind Rivets
Clamping and drilling holes, and inspect matching large flange blind rivets and debug the blind rivet gun before installation.
Insert the rivet vertically into the cleaned hole with its flange closely attached to the workpiece, then use a calibrated rivet gun to steadily clamp and pull the rivet core.
Complete the riveting until the rivet core breaks off, and finally check the connection to ensure it is firm, flat and defect-free.
