When second sourcing PENCOM’s products, PENCOM recommends that the part is tested in the application to ensure that it will meet all performance requirements.
- Punch or drill hole in sheet. Insert a male thread fastener through hole in the sheet and secure the ball stud. In some applications it may be desirable to install a washer between the head of the male threaded fastener and sheet.
- Tighten the assembly by torquing the male threaded fastener 7 to 10 in-lbs (6-32) or 0.8 to 1.1 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 Grade 2 (inch) or Class 4.8 (metric) carbon steel screws and for reference only. PENCOM recommends testing in the application.
- 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.
