Heavy-duty studs with large-diameter heads clinch permanently into thin metal sheets

New PEM® Type THFE™ heavy-duty studs from PennEngineering® clinch permanently into thin metal sheets to provide high-strength attachment. The enlarged head diameter distributes axial tightening force over a wide area to help reduce compressive stress on the host panel, improve pull-through performance, and develop full thread strength. In addition, the thicker head design accommodates larger holes in attached panels.

The self-clinching studs install into steel or aluminum sheets as thin as 0.031 in. with hardness of HRB 85 or less on the Rockwell B scale and HB 165 or less on the Brinell scale. Thread sizes are from ¼-20 through 5/16-18 and M6 through M8. Standard stud lengths are available up to 2 in.
