ISO 13918 Type PT Weld Studs – A2 Stainless Steel
What is an ISO 13918 Type PT Weld Stud?
ISO 13918 Type PT weld studs are metric stainless steel welding studs designed for stud welding, providing a permanent threaded fastening point on sheet metal, plates, and other metal components. The PT designation identifies a threaded weld stud with a reduced welding tip, allowing the stud to be welded directly to the base material using compatible stud-welding equipment.
Unlike conventional bolts that require access to the opposite side of an assembly, weld studs are attached from one side, making them especially useful for applications where rear access is limited or impossible. Once welded in place, the exposed metric thread can accept a nut or other threaded component.
What material are ISO 13918 Type PT Weld Studs made from?
These Type PT weld studs are manufactured from A2 stainless steel, providing excellent general corrosion resistance and durability. A2 stainless is well suited for indoor, outdoor, and moderately corrosive environments where protection against rust and moisture is important.
The stainless steel construction also makes these weld studs an excellent alternative to plated carbon steel studs where a long-lasting, corrosion-resistant threaded fastening point is required. They are available in metric thread sizes and lengths for a wide range of fabrication and assembly requirements.
Why choose ISO 13918 Type PT Stainless Weld Studs?
ISO 13918 Type PT weld studs provide a fast and permanent method of adding metric threaded attachment points to metal components. Stud welding can eliminate the need for drilling, tapping, or installing a conventional bolt through the material, while allowing multiple threaded fastening points to be installed quickly during fabrication.
The A2 stainless steel construction makes these studs particularly useful where corrosion resistance is important. They are a specialty metric fastening component that can be difficult to source in stainless steel, making them valuable for manufacturers, fabricators, and maintenance operations working with European or metric equipment.
Where are A2 Stainless ISO 13918 Type PT Weld Studs commonly used?
These stainless weld studs are commonly used in sheet metal fabrication, automotive manufacturing, machinery, electrical enclosures, HVAC equipment, industrial equipment, food processing machinery, appliance manufacturing, automation systems, and general metal fabrication.
They are especially useful for attaching brackets, panels, shields, covers, electrical components, insulation, cable management hardware, and other components where a permanent metric threaded attachment point is needed. Their one-sided installation makes ISO 13918 weld studs particularly valuable for thin sheet assemblies and applications with limited access to the back side of the workpiece.
