Non-Flush Studs - Types TFH, TFHS - Unified
Check up to five results to perform an action.
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.
Non-flush for sheets as thin as .020”.
Type TFH is recommended for use in steel or aluminum sheets HRB (Rockwell “B” Scale) 80 or less and HB (Hardness Brinell) 150 or less.
Type TFHS is recommended for use in steel or aluminum sheets HRB (Rockwell “B” Scale) 70 or less and HB (Hardness Brinell) 125 or less.
