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 and securely locking the stud into the sheet with high torque-out and pushout resistances.. Also available unthreaded on special order.

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 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.

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.

HFHB (BUBAR^®) Studs are ideal for applications which demand superior electrical/mechanical attachment points. Phosphor bronze studs offer twice the conductivity of carbon steel studs.

FHL (low-displacement head) Studs install closer to the edge of a sheet than standard studs without causing that edge to bulge. Depending on thread size, Type FHL studs can be installed from 25% to 50% closer to the edge of a sheet than standard self-clinching studs.

FH4 & FHP (flush-head) Studs for Sterols Steel are designed to provide strong threads in stainless steel sheets as thin as .040" / 1 mm. Type FHP studs have high corrosion resistance. Both types are designed for use in stainless steel sheets with a hardness of 92 or less on the Rockwell "B" scale.

TPS (flush-head) Pilot Pins satisfy a wide range of positioning, pivot, and alignment applications. The chamfered end makes mating hole location easy.

HFE (high-strength) Studs are designed with an enlarged head diameter to provide high-strength in sheets as thin as .040" / 1 mm.
