FHS-256-5 is a flush-head, self-clinching stud for installation in steel or aluminum sheets as thin as 0.020 in (0.51 mm), with a thread size of #2-56 and a length of 0.250 in. It is designed for sheets with a hardness of HRB 70 or less and HB 125 or less. The stud features a dimpled head for identification and installs flush with the sheet surface, providing high torque-out and pushout resistance. Its head projects above the sheet by 0.025 in (0.64 mm) upon 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.
