Headed Welding Studs with Ferrule Caps

Headed Concrete and Shear Connector Weld Studs are unthreaded fasteners with an upset head and a ferrule ceramic collar. Welding Studs are used in a variety of concrete projects, including the creation of embed plates which attach concrete to a steel frame.

Weld Studs are installed using a drawn arc stud welding gun to create a permanent, high strength bond with an incredibly fast installation time. The Ceramic Collar or cap that the weld studs come with, also known as a Ferrule, help to contain any spatter from the weld by containing and concentrating the heat generated by the weld while also retaining the molten metal for a clean, high quality finished weld. The ferrule is easily broken off afterwords.

Typically, Headed Concrete Studs, also called Anchors, are used for anchoring steel plates and other shapes into concrete while Headed Shear Connector Weld Studs interconnect concrete slabs to load bearing beams where strong shear resistance is needed most. Physically speaking, these two weld studs are the same apart from size: Headed Concrete Studs go up to 5/8" in diameter after which Shear Connector Studs pick up at 3/4" diameter.
