Open-End Blind Rivets (DIN 7337 / ISO 15977)

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 (Open-End Blind Rivets (DIN 7337 / ISO 15977)) 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.

What does the DIN 7337 designation give me when ordering open-end blind rivets?

A fixed dimensional contract: the collected DIN 7337 tables fix the body diameter series 2.4–6.4 mm with tolerances, the head d2 and k series, the joint hole d3 for every body size (a 4.8 mm body wants a 4.9 mm hole), and minimum shear/tensile force per body material — for example 1400 N shear for an aluminium body at 4.8 mm against 2400 N in steel. Order by DIN 7337 (or the equivalent ISO designation your drawing carries) plus body diameter, grip range and body/mandrel material, and the dimensional checks follow from the standard rather than from a maker catalog.

Open end or closed end — which blind rivet do I need?

Decide by what the finished hole must do. An open-end rivet sets fastest and carries the full size ladder, but the set rivet stays hollow through the center — the mandrel channel is open to the outside. If the joint must hold water, dust or pressure, a closed-end rivet seals the body so nothing passes through. For ordinary sheet-metal joints where the hole is not a leakage path, the open-end rivet remains the economical default; size it by grip range — the total stack thickness must sit inside the published range, not at its edge.

Why does the body-and-mandrel material pairing matter?

The body and mandrel do different jobs: the body clamps the sheets and survives the environment, the mandrel only has to survive the set. That is why aluminum body with steel mandrel is the common general-purpose pairing — light, corrosion-resistant head side with enough mandrel strength to set reliably. All-stainless pairs the corrosion resistance on both sides for wash-down or outdoor joints but sets stiffer. Mixed pairs also set a galvanic order — match the body to the thinner or more corrosion-prone sheet so the rivet does not become the anode in the stack.

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.
