Self-Clinching Studs for Stainless Steel Sheets - Types FH4™ and FHP™ - Unified
Flush-Head Studs for Stainless Steel Sheets – Types FH4, FHP
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
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
- Recommended for use in stainless steel sheets HRB (Rockwell “B” Scale) 92 or less and HB (Hardness Brinell) 195 or less.
- Type FHP offers high corrosion resistance and ideal for medical, foodservice, and marine applications.
