This is a trial order for a Hungarian buyer who typically sources from European suppliers. They selected Nuote Metals after reviewing our DIN 7340 product page and verifying our quality documentation.

Product Specification – DIN 7340 A, Copper

DIN 7340 is a German industrial standard that specifies tubular rivets cut from seamless drawn tubing. Unlike hollow rivets produced by deep drawing, DIN 7340 rivets are made from precision tubes, ensuring both inner and outer diameters are perfectly cylindrical with consistent wall thickness. Form A designates a flat head (also known as a countersunk or flattened head).

DIN 7340 designation for this order:

RN A [d1] x [s] x [l] DIN 7340 Cu

Material properties (C11000 ETP copper):

• Electrical conductivity: ≥101% IACS
• Thermal conductivity: ≥388 W/(m·K)
• Tensile strength: ≥205 MPa
• Density: 8.9 g/cm³
• Excellent cold formability and solderability

Quality Certifications & Batch Traceability

All DIN 7340 A tubular rivets in this shipment are backed by full documentation:

ISO 9001:2015 (TÜV SÜD) – active quality management system

Mill test certificate – C11000 copper rod, traceable to heat number

Dimensional inspection report – 100% optical sorting data

RoHS compliance – lead and hazardous substance free

Transparency: The Hungarian buyer requested and received a pre-shipment video showing random samples undergoing dimensional measurement with a laser micrometer. All 20,000 pieces passed 100% optical inspection before packing.

Why Small-Batch Buyers Choose Nuote Metals for DIN 7340

1. Precision tube construction

DIN 7340 rivets are made from seamless drawn tubing, not deep-drawn sheet. This ensures consistent wall thickness and a clean internal bore – critical for electrical feed-through and PCB applications.

2. Copper material advantages

C11000 ETP copper offers excellent electrical conductivity (101% IACS) and corrosion resistance. These tubular rivets are ideal for grounding connections, terminal joints, and solderable assemblies.

3. Low MOQ for trials

Standard MOQ for DIN 7340 rivets is 20,000 pieces – exactly what this Hungarian buyer needed. We accommodate small-batch orders for European clients who want to qualify new suppliers without committing to large volumes.

4. Full DIN 7340 compliance

Our DIN 7340 rivets follow the standard naming convention: RN A [d1] x [s] x [l] DIN 7340 [Material]. This eliminates ambiguity between buyer and manufacturer.

FAQ – DIN 7340 A Copper Tubular Rivets

Q1: What does DIN 7340 A mean, and how is it different from other tubular rivets?

A1: DIN 7340 is a German industrial standard for tubular rivets cut from seamless drawn tubing. “A” refers to Form A – which specifies a flat head (sometimes called a countersunk or flattened head). The standard also defines Form B (knurled round head). The key difference from deep-drawn hollow rivets is the manufacturing process: DIN 7340 rivets are made from precision tubes, which ensures perfectly cylindrical inner and outer diameters with consistent wall thickness. This makes them ideal for applications where a clean internal bore is required, such as electrical feed-through, PCB grounding, and terminal connections. The flat head design sits flush with the workpiece surface, making it suitable for assemblies where a low profile is important.

Q2: What is the MOQ for DIN 7340 copper tubular rivets, and can I get samples?

A2: Our standard MOQ for DIN 7340 rivets is 20,000 pieces per size – exactly what this Hungarian order represents. For first-time European buyers, we accept trial orders from 5,000 pieces. We also provide free samples for sizes we have in stock – the buyer only pays express shipping (DHL or FedEx to Hungary, approximately US$45–US$75). Each sample pack includes 20–50 pieces, a material certificate, and a dimensional inspection sheet. For custom sizes not in stock, we charge a one-time tooling fee (US$200–US$400), fully refundable against a production order of 50,000 pieces or more.

Q3: How do you ensure quality for a small batch of 20,000 pieces?

A3: Quality control is the same regardless of batch size. First, incoming C11000 copper rod is verified against mill test certificates – chemical composition and mechanical properties are confirmed. Second, during production, operators check dimensions every 30 minutes using digital micrometers. Third, 100% of finished parts pass through an optical sorting machine that checks outer diameter, length, head diameter, and surface defects. Fourth, we randomly select samples for destructive testing – including flaring and dimensional verification. All records are kept and shared with the client. The Hungarian buyer received a pre-shipment video showing the entire inspection process.

Q4: Why choose copper (C11000) for tubular rivets instead of brass or steel?

A4: C11000 electrolytic tough pitch copper offers the highest electrical conductivity among common rivet materials – ≥101% IACS. This makes copper tubular rivets the preferred choice for electrical applications such as PCB grounding, terminal connections, and EMI shielding. Copper also provides excellent thermal conductivity (≥388 W/(m·K)), good corrosion resistance, and superior solderability. Brass is more common for decorative or general-purpose applications; steel is used where higher mechanical strength is needed. For this Hungarian buyer’s electrical assembly application, copper was the specified material.
