Threaded Internally Weld Studs incorporate a precision-machined shoulder section between the weld base and threaded portion of the fastener. This design creates a dedicated bearing surface that can be used for positioning, spacing, alignment, or component support while maintaining a permanent welded attachment to the base material.
Commonly used in equipment manufacturing, fabricated assemblies, industrial machinery, and mounting applications, these shoulder weld studs combine fastening functionality with dimensional control. Manufactured for the ARC stud welding process, they are available in carbon steel and stainless steel with multiple thread configurations to accommodate a wide range of engineering requirements.

Threaded Internally Weld Studs incorporate a precision-machined shoulder section between the weld base and threaded portion of the fastener. This design creates a dedicated bearing surface that can be used for positioning, spacing, alignment, or component support while maintaining a permanent welded attachment to the base material.
Commonly used in equipment manufacturing, fabricated assemblies, industrial machinery, and mounting applications, these shoulder weld studs combine fastening functionality with dimensional control. Manufactured for the ARC stud welding process, they are available in carbon steel and stainless steel with multiple thread configurations to accommodate a wide range of engineering requirements.
Designed for applications requiring both threaded attachment and dimensional control, Threaded Internally Weld Studs provide a welded fastening solution with an integrated precision shoulder section.
The machined shoulder creates a consistent bearing surface between the weld base and threaded section. This feature can be utilized for component positioning, alignment, and controlled spacing within assembled structures.
The shoulder and threaded sections perform separate functions within the assembly. The shoulder supports positioning requirements while the threaded portion provides mechanical retention.
Where mounted parts require accurate location relative to the base material, the shoulder section provides a repeatable reference surface that helps maintain assembly consistency.
These threaded weld studs are manufactured for installation using ARC stud welding equipment and are compatible with corresponding ferrules, grips, feet, and chuck assemblies.
Available in UNC, UNF, and metric thread forms, these studs can be matched to project-specific fastening requirements and engineering standards.
Produced in carbon steel and stainless steel, Threaded Internally Weld Studs can be specified for structural, industrial, manufacturing, and corrosion-resistant environments.
Whether you're working from a drawing, replacing an existing stud, or designing a new assembly, we can help identify the correct shoulder diameter, thread specification, and overall length.
