OM-FH (flush-head) 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 flush head assembly and securely locking the stud into the sheet with high torque-out and pushout resistances.
OM-FH4 & FHP (flush-head) Studs for Stainless 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.
FHL (low-displacement head) Studs install closer to the edge of a sheet than PEM Types FH/FHS studs without causing that edge to bulge.
OM-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 push-out resistances.The stud head will not be flush but will project above the sheet surface approximately .025 in./ 0.64 mm.
OM-HFE (high-strength) Studs are designed with an enlarged head diameter to provide maximum pull through in sheets as thin as .040" / 1 mm.
OM-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.
OM-HFHB Studs are ideal for applications which demand superior electrical/mechanical attachment points.Phosphor bronze studs offer twice the conductivity of carbon steel studs.
