Detailed Engineering Specifications

Built to exacting engineering tolerances, this M22 x 148mm Hex Head Cap Screw features a nominal diameter of 22mm and a total length of 148mm, with a head width measuring 28mm. The intrinsic properties of polycarbonate provide excellent resistance to a broad spectrum of chemicals and solvents, making it ideal for corrosive environments where metal fasteners would degrade. Furthermore, its non-conductive nature makes it a safe choice for electrical applications, preventing short circuits. This material also offers good impact strength and a wide operating temperature range, ensuring consistent performance across various conditions.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, leading to thread stripping or cracking of the polycarbonate head.Use a torque wrench set to the manufacturer's recommended torque value for polycarbonate fasteners to avoid over-stressing the material.
Using metal tools that can scratch or damage the polycarbonate surface.Employ tools made from softer materials (e.g., nylon, brass) or ensure careful handling with metal tools to preserve the surface integrity.

Common Applications

  • Chemical processing equipment
  • Electrical enclosures and assemblies
  • Marine and coastal applications
  • Food and beverage processing equipment

⚠️ Engineering Warnings

  • Not suitable for applications requiring high tensile strength or high-temperature resistance beyond the material's limits.
  • Avoid exposure to strong UV radiation for prolonged periods without UV stabilization, as it can degrade the material over time.
