Installation Procedure

1. Select the appropriate mating component with a tapped M13 hole or nut. 2. Insert the hex head cap screw and hand-tighten to establish thread engagement. 3. Use a standard hex wrench to tighten the screw to the desired torque, avoiding over-tightening to prevent stripping.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, which can lead to thread stripping or material fracture.Apply torque incrementally and stop when resistance increases significantly. Use a torque wrench for precision if required.
Using the wrong tool size for the hex head, potentially damaging the head or the tool.Ensure a snug fit with the correct size hex wrench (typically 10mm or 11mm for an M13 head width of 13mm).

Common Applications

  • Electrical enclosures and equipment mounting
  • Medical device assembly
  • Food processing machinery
  • Corrosive chemical handling systems

⚠️ Engineering Warnings

  • Not recommended for structural load-bearing applications where high tensile strength is critical.
  • Avoid exposure to strong alkalis or certain aromatic hydrocarbons, which can degrade polycarbonate.
