Structural Blind Rivets
Structural blind rivets — high-strength break-mandrel rivets with mechanically locked mandrels, engineered for higher shear and tensile strength and vibration resistance than standard blind rivets. Aluminum, steel and stainless bodies for truck, trailer, rail and industrial assembly.

Specifications
Structural blind rivets are the heavy-duty end of the break-mandrel line: same one-sided installation, but a stronger body, a mandrel that is retained or mechanically locked into the set rivet, and joint ratings engineered a class above standard blind rivets. The locked mandrel is the tell — it fills the body bore instead of leaving it open, which raises both strength and vibration behavior on moving equipment. The collected industry material lists the range across aluminum, steel and stainless bodies with dome, large flange and countersunk heads, and puts the working envelope in truck and trailer bodies, commercial vehicle panels, rail equipment, metal fabrication and industrial enclosures — anywhere loads, vibration and one-sided access coincide. Selection follows the same three questions as any blind rivet: grip range covers the total stack thickness, hole size meets the rivet requirements, and the shear/tensile ratings meet the joint loads. Strength figures vary by body line, so rate the joint from the specific product datasheet, not from the family name.
| Type | Structural (high-strength) blind rivet — locked or retained mandrel, one-sided installation |
|---|---|
| Strength positioning | Engineered for higher shear and tensile strength and vibration resistance than standard blind rivets (per collected industry material); numeric ratings vary by body line — see the representative series data below and confirm from the selected product datasheet |
| Mandrel retention | Mandrel retained or mechanically locked in the rivet body — supports joint strength under vibration; no open bore through the set rivet |
| Materials | Aluminum, steel or stainless steel bodies; mandrel material per body line |
| Head styles | Dome, large flange, countersunk |
| Selection inputs | Total material thickness inside the published grip range; hole diameter per the rivet requirements; shear and tensile loads against the body-line ratings |
| Applications | Truck and trailer bodies, commercial vehicle panels, rail and transport equipment, metal fabrication, cabinets and enclosures |
| Representative series data | Howmet Huck Magna-Lok circle-lock line — sizes 3/16, 1/4, 3/8, 1/2 in; heads protruding, truss, 100° flush; hole sizes .191–.201 / .261–.272 / .392–.408 / .531–.563 in |
| Grip range scope (Magna-Lok) | Stepped per part number: 3/16 in from .062 to .665; 1/4 in from .080 to 1.375; 3/8 in .120–.625; 1/2 in .160–.750 |
| Minimum shear — steel body | 1,300 lbf (3/16) · 2,500 lbf (1/4) · 6,000 lbf (3/8) · 10,000 lbf (1/2), protruding head |

Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (Structural Blind Rivets) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantity is 10,000–50,000 pieces depending on size. Standard production run 10–20 days. Quantities or variants outside the standard range are confirmed at quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
When do I need a structural blind rivet instead of a standard one?
Rate the joint first. Standard open-end blind rivets carry light sheet-metal loads fine; a structural rivet earns its place when the joint sees sustained shear or tensile load, vibration, or movement — truck bodies, trailers, rail interiors, chassis-mounted equipment. The design differences are functional, not cosmetic: a stronger body, and a mandrel that locks into the bore so the set rivet does not loosen or rattle under vibration. If your joint is a thin enclosure panel, stay standard; if the fastener is part of the structure, move to the structural line and rate it from the body-line datasheet.
What is the MOQ and lead time for these rivets?
Minimum order quantity is 10,000–50,000 pieces depending on size and material. Standard production lead time is 10–20 days. Common blind rivet sizes are widely stocked — confirm the exact schedule against quantity and size mix at quotation.
What should an RFQ for these rivets state?
State the rivet subtype (open-end, closed-end, structural blind rivet or rivet nut), body diameter, grip range or total material thickness, head style (dome, countersunk or large flange), body and mandrel materials (for example aluminum body with steel mandrel, or all-stainless), finish, required certificates such as a mill test report per EN 10204 3.1, and quantity per size — plus destination country.
