# Welding Screws, coarse thread, \u00d8 5 \u00d7 14.2 mm<\/p>\n
**Part Number: 297052**<\/p>\n
This product is part of the Wiel\u00e4nder+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.<\/p>\n
## Product Description and Key Features<\/p>\n
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.<\/p>\n
**Key Features:**<\/p>\n
* **Material Quality:** High-strength steel, grade 4.8. This material selection ensures optimal weldability and durability.
\n* **Surface Treatment:** The screws are copper-plated. This coating is critical during the resistance welding process as it improves electrical conductivity and minimizes sparking, thus contributing to a clean and strong weld joint.
\n* **Thread Type:** Coarse thread (Grobgewinde). The coarse thread ensures excellent hold and is more resistant to damage, which is advantageous at frequently used fastening points.
\n* **Application Area:** Primarily used as a consumable welding item for single-sided spot welding guns (Single Sided Spot Welding Gun GT).<\/p>\n

## The Significance of Copper Plating and Steel Core<\/p>\n
The performance of welding screws depends significantly on their material composition and surface treatment.<\/p>\n
**Steel Core (4.8):** The grade 4.8 strength class steel ensures that the screw can withstand the thermal load and mechanical stress during welding without deforming or losing its fastening capacity. This standard quality is ideal for the temporary or permanent fastening of most body components.<\/p>\n
**Copper Plating:** Copper is an excellent electrical conductor, which is crucial for resistance welding. During the welding process, the 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 transfer and consequently a homogeneous, strong weld nugget. Furthermore, the copper coating prevents the overheating of the screw head and the rapid wear of the electrode.<\/p>\n
## Compatibility and Application Environment<\/p>\n
These welding screws are closely related to Wiel\u00e4nder+Schill welding technology systems, especially single-sided spot welding guns. The precise dimensioning (\u00d8 5 mm diameter and 14.2 mm length) ensures quick and efficient fastening on body panels where access is only possible from one side.<\/p>\n
**Application Areas:**<\/p>\n
1. **Temporary Fastening of Body Elements:** Used to secure the positioning of parts to be repaired or replaced before final placement.
\n2. **Preparation of Welding Points:** The screws can be used in areas where conventional spot welding is not possible due to lack of access.
\n3. **Joining Sheets of Different Thicknesses:** These screws assist in securing metal sheets of varying thicknesses together prior to welding.<\/p>\n
## Available Dimensions (Similar Products)<\/p>\n
