TFHS non-flush self-clinching studs are designed for installation in steel or aluminum sheets as thin as 0.51 mm, with the stud head projecting above the sheet surface by 0.64 mm. They are recommended for use in sheets with a Rockwell B hardness of 70 or less and a Brinell hardness of 125 or less. The TFHS-M4-15 is a metric variant with an M4 x 0.7 thread, a minimum hole size of 4.5 mm, and a maximum panel thickness of 5.8 mm that allows for secure clinching. The stud length is 15 mm, and the part is suitable for panels with nominal thicknesses up to 5.8 mm. The head features a dimple to identify it as a TFH/TFHS stud.
PEM® self-clinching studs are installed by placing them in properly sized holes in the sheets and squeezing into place with any standard press. The squeezing action embeds the head of the stud into the sheet. The metal displaced by the head flows smoothly and evenly around the ribs and into the annular groove - creating a flushhead assembly and securely locking the stud into the sheet with high torque-out and pushout resistances.
TFH (non-flush) Studs are for sheets as thin as 0.51mm. They may also be used in thicker sheets where flush head studs are not required. TFH studs are installed in the sheets in the same manner as flush-head studs; however, different punches and anvils are required. When installed, the TFH stud will be securely locked into the thin sheet with ample torque-out and pushout resistances. The stud head will not be flush but will project above the sheet surface approximately 0.64mm.
