Detailed Engineering Specifications

Built to exacting engineering tolerances, this M4 x 36mm polycarbonate hex head cap screw features a 7mm head width for secure fastening. Polycarbonate's inherent properties provide excellent impact strength, UV resistance, and a wide operating temperature range (-40°C to +120°C). Its non-conductive nature makes it ideal for applications where electrical isolation is critical, such as in electrical enclosures, sensitive electronic assemblies, and medical equipment. The material's good chemical resistance also extends its usability in environments exposed to mild acids, alkalis, and oils, ensuring long-term performance and reliability.

Installation Procedure

1. Select the appropriate tool (e.g., hex wrench) of the correct size for the M4 head. 2. Align the screw with the pre-drilled or tapped hole. 3. Hand-tighten the screw initially to ensure proper thread engagement. 4. Use the hex wrench to tighten the screw to the desired torque, avoiding over-tightening to prevent material deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to thread stripping or head cracking.Use a torque wrench set to the manufacturer's recommended torque value for polycarbonate fasteners or tighten with moderate hand pressure.
Using metal washers that can cause galvanic corrosion or damage the polycarbonate surface.Employ washers made of compatible materials, such as nylon or other plastics, to protect the polycarbonate and maintain its insulating properties.

Common Applications

  • Electrical enclosures and control panels
  • Medical device assembly
  • Food processing equipment
  • Corrosion-sensitive environments

⚠️ Engineering Warnings

  • While impact-resistant, avoid exposing to sharp impacts or excessive abrasive forces.
  • Do not use in applications requiring high tensile strength or where significant mechanical load is present without proper engineering validation.
