135mm 185mm 210mm Spot Weld Pins for Industrial and Marine Insulation | Customizable

Spot weld pins are precision-engineered fasteners designed for securely attaching insulation materials to metal surfaces in demanding industrial and marine environments. Installed with CD or stud welding machines, these pins offer strong, permanent attachment, ensuring insulation remains stable under vibration, high temperatures, and corrosive conditions.

After welding, insulation is impaled on the pin and fixed with a self-locking washer, providing long-term stability and maintaining thermal efficiency. Spot weld pins are widely used in shipbuilding, industrial HVAC systems, pipelines, power plants, and other heavy-duty insulation applications.

Material Options & Advantages

Our spot weld pins are available in high-quality materials to suit different project needs:

• Copper-Plated Steel – Excellent corrosion resistance for marine projects

• Zinc-Plated Steel – Cost-effective and suitable for general industrial use

• Stainless Steel 304 / 316 – Durable and corrosion-resistant for harsh environments

• Custom Materials – Available upon request for specialized applications

All pins are produced under strict quality control to ensure consistent dimensions, weldability, and holding strength. Custom lengths, diameters, and base types are available for project-specific requirements.

Specifications

• Pin length should exceed insulation thickness for secure self-locking washer installation

• Standard nail point, with blunt end available as special order

• Compatible with all standard CD and stud welding machines

Additional Notes:
These spot weld pins are designed to provide maximum performance in industrial and marine environments. Proper installation ensures strong attachment, reduces the risk of insulation detachment, and maintains long-term stability. Custom lengths and base types are available to accommodate unique insulation systems.

Applications

• Marine insulation, including ship decks and engine rooms

• Industrial wall, roof, and tank insulation

• HVAC systems in marine and industrial facilities

• Power plants, petrochemical, and chemical processing insulation

• High-temperature or vibration-prone industrial equipment

Using spot weld pins guarantees insulation layers remain firmly attached, preserving structural integrity and reducing maintenance needs. Their compatibility with CD and stud welding machines makes them ideal for large-scale industrial and marine insulation projects.
