Wielander+Schill Die Set V1 + V2 for Solid Self-Piercing Rivets | 700350

The Wielander+Schill Die Set V1 + V2 (SKU: 700350) is an essential, precision-engineered die kit designed explicitly for the installation of Solid Self-Piercing Rivets (SPR) in modern automotive collision repair. As OEMs increasingly utilize advanced high-strength steels and mixed-material bonding, solid self-piercing rivets have become a mandatory joining method for major brands such as Mercedes-Benz and Audi.

This set consists of two specifically profiled closing and setting dies (V1 and V2) that seamlessly integrate with industry-leading Wielander+Schill riveting tools, including the XPress 800, XPress 1000, and XPac series. Machined from ultra-hardened tool steel, these dies are built to withstand the immense hydraulic and pneumatic forces required to drive solid rivets through structural panels, ensuring a perfect, factory-grade mechanical joint without deforming the surrounding metal.

Key Features

• OEM-Approved Joining: Specifically designed to meet the strict riveting standards required by European and domestic OEMs for structural panel bonding using solid SPRs.

• Precision Geometry: Both the V1 and V2 dies are expertly machined to cup and control the solid rivet head and tail during the pressing cycle, preventing rivet tumbling or panel distortion.

• Complete 2-Piece Set: The kit includes both the required setting die (V2) and the closing die (V1) for a complete, out-of-the-box solution to solid SPR installations.

• High-Strength Durability: Manufactured from industrial-grade hardened steel to endure the immense pressure of professional heavy-duty rivet guns over thousands of cycles.

• Quick-Change Integration: Engineered for the rapid-change magnetic die holders of Wielander+Schill's XPress and XPac riveting systems, minimizing downtime during complex multi-rivet repairs.

Technical Specifications

Ideal Use Cases & Applications

• Mercedes-Benz & European Collision Repair: A staple component in OEM repair kits (such as the Tool Box RS-07 for Mercedes-Benz), used heavily when replacing B-pillars, structural nodes, and rocker panels.

• Mixed-Material Bonding: Essential for joining aluminum to high-strength steel or when securing thick structural stacks where traditional semi-tubular rivets or spot welds are not permitted.

• High-Strength Steel Installations: The specialized V1 and V2 profiles are required when pushing solid rivets through hardened boron or ultra-high-strength steel (UHSS) structures safely.

Common Questions (FAQs)

Q: What is the difference between solid SPRs and semi-tubular SPRs?
A: Semi-tubular rivets are hollow at the bottom and flare out inside the bottom layer of metal to create an interlocking joint. Solid SPRs are completely solid slugs that punch fully through the metal stack and require specialized dies (like this V1/V2 set) to form and secure the joint.

Q: Are these dies compatible with rivet guns from other brands?
A: These dies are specifically engineered with the correct shank diameter and profile to fit the C-arms and adapters of Wielander+Schill systems (XPress 1000, XPac, etc.). While they may physically fit in some other guns, they are certified and tested for W+S equipment.

Q: Can I purchase the V1 or V2 dies separately?
A: While replacement parts can sometimes be sourced through specialized OEM catalogs (under parts 700333 and 700277), it is highly recommended to replace both the setting and closing dies simultaneously as a set (SKU: 700350) to ensure even wear and a perfectly aligned rivet press.
