FHS-M4-8 is a flush-head, self-clinching threaded stud designed for installation in aluminum, steel, or stainless steel sheets as thin as 0.51 mm. It is recommended for use in materials with a Rockwell B hardness of 70 or less and a Brinell hardness of 125 or less, providing high torque-out and pushout resistance. The stud installs permanently using a standard press and features a flush head that remains level with the sheet surface after installation.
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.
FH (flush-head) studs are available in aluminum, steel, or stainless steel. They are also available unthreaded on special order.
