This product is part of the Wieländer+Schill welding technology range, specifically designed for resistance spot welding machines (Single Sided Spot Welding Gun GT), a high-quality weldable consumable. These steel screws are ideal for body repair work where reliable and durable fastening points are required.
The product meets the highest professional requirements, ensuring efficient and precise work performance in the workshop environment.
These weldable screws are made from 4.8 grade steel, and have a standard metric thread. Their surface is copper-plated,, which provides excellent conductivity and corrosion protection during the welding process, minimizing sparking and optimizing weld seam quality.
The screws are primarily used for temporary or permanent fastening of body panels where the welding process is the most suitable joining method. The 4.8 quality grade guarantees the necessary mechanical strength for typical automotive applications.
The product packaging is ideal for quick and efficient work, as one package contains 50 screws of the same specification.
The table below details the precise physical and material characteristics of the weldable screws:

Material and Strength: The 4.8 grade steel base material ensures that the bolt can withstand the thermal load generated during the welding process and subsequent mechanical stress. This standard quality is widely accepted in automotive repairs.
Copper Plating: The copper coating is critically important for resistance spot welding. It helps increase the lifespan of the welding electrodes by reducing sticking and improving current transfer, resulting in a more uniform and stronger weld seam.
Sizing: The M4 metric thread is standardized, allowing the use of standard M4 nuts or other fasteners over the weld bolt. The 15 mm thread length is sufficient for most fastening tasks.
Compact Design: The external dimensions of 16 x 5.5 x 5.5 mm (likely the head dimensions) indicate that the bolt has a relatively low profile, which can be advantageous when working in tight spaces.
These weld bolts are specifically designed for the range offered by Wieländer+Schill Single Sided Spot Welding Gun GT consumables optimized for the (Single Sided Spot Welding Gun GT) series. Combined with the appropriate welding equipment, they guarantee fast and repeatable quality fastening.
The product is recommended for fastening any body element where conventional riveting or bolting is not possible due to lack of access, or where a welded connection is preferable for structural integrity.
Wieländer+Schill is committed to the highest quality standards. The manufacturing and distribution of the product comply with international quality management systems, as evidenced by the following certificates:
ISO 9001: Quality Management System
ISO 14001: Environmental Management System
These certificates ensure that the manufacturing process for the weld bolts is strictly controlled and documented, guaranteeing continuously high product quality.
This product is an essential accessory for modern, professional body repair shops where efficiency and durability are paramount.
