Why Access Decides the Rivet, Not Load Alone
It’s tempting to choose a rivet purely by strength requirement, but access reality comes first every time. A solid rivet forms its driven head by bucking — someone has to hold a bar against the tail while the head is formed from the accessible side, which simply requires both faces of the joint to be reachable during assembly. There is no strength number that changes that physical requirement.
A blind rivet exists purely to remove that requirement — its mandrel-pull mechanism forms the retaining head entirely from one accessible face, which is why it’s the only real option in closed box structures, sealed fuel tank sections, or thin tubular members where the far side genuinely cannot be reached. Once access is confirmed as the deciding factor, strength, material, and head style become the next questions to work through.
Akbar Fasteners Pvt. Ltd. exports to over 50 countries, and both our solid and blind rivet ranges are manufactured with controlled dimensional and material properties, verified using NASM1312 shear test methods under our ISO 9001:2015 quality system.
Where This Category Genuinely Applies
Correct Rivet for the Access Reality
Choosing solid vs blind by actual joint access, not just strength, avoids assembly-stage surprises.
Genuine Flush-Surface Option
MS20426’s countersunk head gives real aerodynamic benefit on external skin surfaces.
Genuine Closed-Structure Option
MIL-DTL-32258’s blind mechanism reaches wing box and sealed structure no solid rivet can.
Verified Shear & Material Properties
Batch testing under defined NASM1312 methods confirms genuine strength for the ordered material and size.
Solid and Blind Rivets in Detail
MS20426 Countersunk Rivets
100° flush countersunk solid rivets in 2117-T4 and 2017-T4 aluminum alloy, for external aerodynamic skin surfaces where both sides of the joint are accessible during assembly.

Mandrel-pull blind rivets across aluminum, steel-mandrel, and Monel options, for closed box structures and sealed assemblies where the far side of the joint cannot be reached.
View MIL-DTL-32258 →Solid vs Blind — Quick Reference
Confirming access before anything else avoids specifying a rivet that can’t physically be installed. This table is the quick reference we use with buyers before quoting.
| Aspect | MS20426 Solid Rivet | MIL-DTL-32258 Blind Rivet |
|---|---|---|
| Access Required | Both sides (bucking bar needed) | One side only |
| Head Profile | Flush, 100° countersunk | Domed or countersunk |
| Typical Strength | Generally higher for equivalent size | Good, application-dependent |
| Best Suited For | External aerodynamic surfaces | Closed structures, blind access |
