INSTALLATION

  1. Punch or drill hole in sheet. Insert the ball stud male thread through hole in sheet and secure with female threaded fastener. In some applications it may be desirable to install a washer between the female threaded fastener and sheet.
  2. Tighten the assembly by torquing the female threaded fastener 5.8 to 7.9 in-lbs (6-32) or 0.53 to 0.72 N-m (M3.5). PENCOM recommends a minimum thread engagement of .138 in (6-32) or 3.5 mm (M3.5) between the male and female threads. Installation torques are for zinc–plated carbon steel ball studs and nuts, and for reference only. Pencom recommends testing in the application.
  3. Due to the inelastic nature and unpredictable friction coefficients of stainless steel, torque calculations for this material can be unreliable. One method of determining the installation torque uses 50% of the failure torque as developed through testing in the application and applying a ±20% tolerance.
