Self-locking washers, commonly called Speed Clips, are designed to secure insulation after weld pins have been installed using ARC or CD stud welding. Once the insulation is impaled over the weld pin, the washer is pressed onto the pin to create a permanent mechanical hold without additional fasteners.
Complete Stud Welding supplies square and round speed clips in multiple materials and sizes for HVAC, industrial insulation, and thermal protection systems.
Self-Locking Washers, also known as Speed Clips, provide a fast and dependable method for securing insulation after weld pins have been installed. Their internal locking mechanism firmly grips the pin to create a permanent mechanical hold without requiring additional hardware.
Available in both square and round configurations, these insulation fasteners are manufactured in galvanized steel, stainless steel, and aluminum for use in HVAC, industrial, commercial, and thermal insulation systems.
