# C3 + C4 Tool Set for Flow Form Rivets | \u00d8 8 mm<\/p>\n
This detailed product description presents the tool set belonging to the Wiel\u00e4nder+Schill professional body repair tools, specifically designed for installing 8.0 mm diameter Flow Form Rivets (FFR). The set consists of two essential key components required for precise and reliable riveting work, which are part of the XSeries \u2013 Professional Riveting Technology product family.<\/p>\n
## Overview and Application<\/p>\n
The **part number 700338** tool set aims to provide optimal conditions for the professional installation of high-strength, 8.0 mm diameter flow form rivets. The application of these rivets is critical for joining modern vehicle body elements, especially high-strength steel and aluminum alloys, where welding is not applicable or desired. The set guarantees a standard-compliant, durable, and aesthetic joint.<\/p>\n
This tool set is composed of the following two main components:<\/p>\n
1. **C3 | Setting Die**
\n2. **C4 | Closing Die**<\/p>\n
The professional design ensures a long service life and consistent performance, even under heavy use, making it ideal for workshops and service centers.<\/p>\n
## Technical Specifications and Package Contents<\/p>\n
The product has been developed according to Wiel\u00e4nder+Schill's quality standards, ensuring precise fit and efficient operation.<\/p>\n

### Detailed Set Contents<\/p>\n
The 700338 tool set contains the following individual components that work in synergy with each other:<\/p>\n
#### 1. C3 | Setting Die for Flow Form Rivets (FFR)<\/p>\n
* **Part Number:** 700266
\n* **Function:** This tool is responsible for preparing the head of the flow form rivet and inserting the rivet body into the base material, as well as shaping the rivet stem for the closing operation.
\n* **Application:** Specifically optimized for 8.0 mm diameter FFR rivets.
\n* **Advantages:** Its precise design ensures the rivet head sits flush with the body surface, minimizing damage and stress around the joint.<\/p>\n
#### 2. C4 | Closing Die for Flow Form Rivets (FFR)<\/p>\n
* **Part Number:** 700267
\n* **Function:** Final forming of the end of the rivet stem prepared by the C3 tool, creating the solid, controlled closing head on the backside of the body panel.
\n* **Application:** Compatible with 8.0 mm diameter FFR rivets.
\n* **Advantages:** The C4 tool ensures optimal deformation of the rivet closing face, which is essential for achieving maximum tensile strength and vibration resistance.<\/p>\n
## Flow Form Riveting Advantages and the Role of the Tools<\/p>\n
Flow Form Riveting (FFR) technology is a modern process that creates high-strength joints without requiring the rivet material to be pre-punched or threaded. During the process, the tools (C3 and C4) press the rivet using hydraulic or pneumatic force, resulting in the cold flow (flow forming) of the rivet material.<\/p>\n
**Advantages of the C3 + C4 Set:**<\/p>\n
* **High Joint Strength:** The joint created through the cold forming process often surpasses the strength of traditional rivets, especially in the case of high-strength materials.
\n* **Material Compatibility:** Ideally suited for joining sheets of different thicknesses and strengths, such as MS (Mild Steel), HSLA (High-Strength Low-Alloy), or AHSS (Advanced High-Strength Steel) materials used in modern vehicles.
\n* **Precise Geometry:** The special contours of the tools guarantee that the rivet closing head fits precisely to the manufacturer's specifications, which is essential for maintaining the structural integrity of the body.
\n* **Professional XSeries Quality:** As a member of the Wiel\u00e4nder+Schill XSeries product line, these tools meet the highest industrial requirements, ensuring reliable and repeatable results.<\/p>\n
## Additional Information<\/p>\n
The use of this tool set requires a compatible riveting machine capable of providing the force and stroke length necessary for installing 8.0 mm FFR rivets.<\/p>\n
**Related Accessories (Zubeh\u00f6r):**<\/p>\n
Although the 700338 set alone provides a complete solution for 8 mm FFR rivets, the C3 and C4 tools are also available separately in the Wiel\u00e4nder+Schill assortment in case replacement or special requirements arise:<\/p>\n
* **Part Number 700266:** C3 Setting Tool (available separately)
\n* **Part Number 700267:** C4 Closing Tool (available separately)<\/p>\n
