Part Number: 297052
This product is part of the Wieländer+Schill welding technology range, a high-quality consumable specifically designed for resistance spot welding machines (Single Sided Spot Welding Gun GT). These copper-plated steel welding screws with coarse thread are essential for body repair work, ensuring reliable and durable fastening.
Welding screws with part number 297052 are ideal for professional body building and repair applications. The product is made of high-quality 4.8 strength class steel, which guarantees the necessary mechanical strength during the welding process and in the final structure.
Key Features:
Material quality: High-strength steel with 4.8 quality rating. This material choice ensures optimal weldability and durability.
Surface treatment: The screws are copper-plated. This coating is critically important during the resistance welding process as it improves electrical conductivity and minimizes sparking, thus contributing to a clean and strong weld connection.
Thread design: Coarse thread (Grobgewinde). The coarse thread provides excellent grip and is more resistant to damage, which is advantageous for frequently used fastening points.
Area of application: Used primarily as a welding consumable for single-sided spot welding guns (Single Sided Spot Welding Gun GT).
Accurate dimensions and specifications ensure compatibility with the appropriate welding equipment and precise execution of work.

The performance of welding screws depends significantly on their material composition and surface treatment.
Steel Core (4.8): The 4.8 strength class steel ensures that the screw can withstand the heat load and mechanical stress generated during welding without deforming or losing its fastening capacity. This standard quality is ideal for the temporary or permanent fastening of most body parts.
Copper Plating: Copper is an excellent electrical conductor, which is crucial for resistance welding. During the welding process, current flows across the screw head. The copper plating reduces the contact resistance between the welding electrode and the screw, resulting in more uniform current transmission and thus a homogeneous, strong weld spot. Furthermore, the copper plating prevents overheating of the screw head and premature wear of the electrode.
These welding screws are closely related to Wieländer+Schill welding technology systems, especially single-sided spot welding guns. The precise dimensioning (Ø 5 mm diameter and 14.2 mm length) ensures quick and efficient fastening on body panels where access is only possible from one side.
Application areas:
Temporary fastening of body parts: For securing the position of parts to be repaired or replaced prior to final assembly.
Preparation of welding points: The screws can be used in areas where traditional spot welding is not possible due to lack of access.
Joining sheets of different thicknesses: Using the screws, metal sheets of different thicknesses can be fastened together before welding.
Although the current product represents the 14.2 mm length, the series is also available in other dimensions to meet different application requirements:
T5 × 9.0 mm
T5 × 14.2 mm (Current product)
T5 × 18.0 mm
T5 × 25 mm
This selection allows the user to always choose the optimal screw length corresponding to the workpiece thickness.
