Weld Studs
Projections Below the Head
Projections Above the Head
These studs have a wide base that distributes the load and projections that concentrate the weld. Length listed is overall length.
Choose studs with below-head projection for a stronger hold that uses the full strength of the fastener. Pass these studs through a hole and weld them in place.
Choose studs with above-head projection to weld the screw directly to the surface of the material for a smoother appearance.
