SELF-CLINCHING STUDS AND PINS Revised 606 SELF-CLINCHING STUDS AND PINS FH (flush-head) Studs are installed by placing them in punched or drilled 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 flush-head assembly Flush-head Studs. and securely locking the stud into the sheet with high torque-out and pushout resistances. (See page FH-4). Also available unthreaded on special order. (See page FH-5) TFH (non-flush) Studs are for sheets as thin as .020 inches / 0.51 mm. 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 Thin Sheet Studs. 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. / 0.64 mm. (See page FH-6) High-strength Studs. HFH (high-strength) Studs replace weld studs with easier installation at lower costs. The large stud head which projects above the sheet material distributes the axial tightening force over a large area thereby improving pull through resistance. (See page FH-7) ® HFHB (BUSBAR ) Studs are ideal for applications which d
