Knurled Weld Studs are insulation-fastening weld studs designed to secure thermal insulation and exterior metal jacketing to steel surfaces. The knurled section locks a matching drive plate in place after the insulation is installed, creating a dependable mechanical fastening point.
Installed using the ARC stud welding process, knurled weld studs are available in mild steel and stainless steel for insulation systems used on tanks, vessels, ductwork, piping, and industrial process equipment. Complete Stud Welding supplies Knurled Weld Studs in mild steel and stainless steel for insulation systems used on tanks, process vessels, piping, ductwork, and industrial equipment, with compatible accessories available for complete installation.

Knurled Weld Studs are insulation-fastening weld studs designed to secure thermal insulation and exterior metal jacketing to steel surfaces. The knurled section locks a matching drive plate in place after the insulation is installed, creating a dependable mechanical fastening point.
Installed using the ARC stud welding process, knurled weld studs are available in mild steel and stainless steel for insulation systems used on tanks, vessels, ductwork, piping, and industrial process equipment. Compatible accessories are also available to complete the installation system.
Knurled weld studs combine welded attachment with mechanical retention for insulation fastening, and their matched accessories help simplify installation and maintain consistent performance.
The knurled section features a 0.327" diameter that steps from the 0.312" stud base, providing a secure fit as the drive plate is hammered past the 0.375" groove, creating a permanent friction-lock.
These specialized pins comply with galvanic insulation requirements and can be paired with TKN-001 Mild Steel or TKN-002 Stainless Steel Drive Plates, addressing various metallurgy needs.
Knurled weld studs utilize drawn arc welding to create a full-cross-section weld with no pre-drilling, establishing a strong anchor point that exceeds the tensile strength of both the pin and base steel.
Each 0.312" base stud includes an F031-F ceramic arc ferrule, which molds the molten steel into a 0.438" diameter by 0.109" high fillet ring, ensuring structural stability without damaging insulation.
The Knurled Weld Stud series is designed for high-volume automation and fits seamlessly into standard production equipment, compatible with the CN-031 weld chuck, GN-031 ferrule grip, and B-1N heavy foot assembly for efficient placement.
Choosing compatible weld studs, drive plates, ferrules, grips, feet, and chucks is crucial for efficient installation and reliable insulation retention. Complete Stud Welding provides full fastening systems and the necessary ARC weld stud accessories for industrial insulation projects.
