Projection-Weld Threaded Studs

38 products

Projection-weld threaded studs are fasteners that are welded to or through a metal surface to create a permanent male thread. They have raised weld points (projections) to better control placement of the fastener than by welding the entire head. Weld in studs are ideal for use in heavy duty applications, such as those in the construction and automotive industries. Projection stud welding is used in hard-to-reach places, such as narrow channels and other confined spaces.

The studs are secured to the workpiece by welding the projections on the underside of the flange.
