TFHS non-flush self-clinching studs are designed for installation in aluminum or steel sheets as thin as 0.020 in. (0.51 mm), with the head projecting approximately 0.025 in. (0.64 mm) above the sheet surface. 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 stud features a threaded M4-0.7 or UNC thread depending on configuration and is installed using standard press tools with specific dimple-indented heads for identification. The part TFHS-032-14 corresponds to a #10-32 thread size with a length code indicating 14/16 in. (0.875 in.) unthreaded length, compatible with sheets rated up to HRB 70 and HB 125.
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 .020 inches. 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 .025 in.
