PEM® FH4 self-clinching studs provide externally threaded attachment points in stainless steel sheets as thin as .040" (1.02 mm), with corrosion resistance suitable for applications requiring 300-series stainless steel performance. They are designed for installation in stainless steel sheets with a hardness of HRB 92 or less. The stud installs flush, creating a secure, permanent attachment through deformation of the host material. The part series includes variants identified by thread size, with FH4-440-6 corresponding to a .112-40 thread. All members of the series require proper hole size and sheet thickness to ensure successful clinching. Custom sizes are available upon special order.
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.
FH4 & FHP (flush-head) Studs for Stainless Steel are designed to provide strong threads in stainless steel sheets as thin as .040” . 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
