Stainless Stud Welding Insulation Pins Dome Cap Washer Insulation Fasteners

Stud welding insulation pins are high-performance fasteners designed to attach insulation materials securely to metal surfaces in demanding industrial and marine applications. Installed using stud welding machines, these pins provide rapid, strong, and permanent attachment, ensuring insulation remains stable even under vibration, high temperatures, or harsh environments.

Once welded in place, insulation is impaled on the pin and secured with a self-locking washer, providing long-term durability and maintaining thermal efficiency. These pins are widely used in shipbuilding, power plants, petrochemical facilities, and other industrial insulation projects.

Material Options & Advantages

Our stud welding insulation pins are manufactured in a variety of materials to meet project requirements:

• Copper-Plated Steel – Excellent corrosion resistance, especially for marine applications

• Zinc-Plated Steel – Cost-effective solution for general industrial insulation

• Stainless Steel 304 / 316 – High durability and corrosion resistance in aggressive environments

• Custom Materials – Available for specialized insulation projects

All pins are produced under strict quality control standards, ensuring consistent dimensions, strong weldability, and reliable holding performance. Custom lengths, diameters, and base types are available to meet specific project needs.

Specifications

• Pin length should exceed insulation thickness to securely attach the self-locking washer

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

• Compatible with all standard stud welding machines

Additional Notes:
These stud welding insulation pins are designed for optimal performance in industrial and marine environments. Correct installation with stud welding machines ensures maximum holding strength, reduces insulation detachment risk, and maintains long-term stability under vibration, thermal cycling, or corrosive conditions. Custom lengths and base types are available upon request.

Applications of Stud Welding Insulation Pins

• Marine insulation, including engine rooms and decks

• Industrial wall, roof, and tank insulation

• HVAC systems for industrial and marine facilities

• Power plants and energy facilities

• Petrochemical and chemical processing insulation

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