Engineered for reliability and performance, this M15 x 73mm Hex Head Cap Screw features a substantial 31mm head width for superior torque application. Fabricated from advanced polycarbonate, it offers outstanding impact strength, high tensile strength, and excellent dielectric properties, making it ideal for electrically sensitive areas. The material also provides superior corrosion and chemical resistance compared to traditional metal fasteners, ensuring longevity in aggressive or humid conditions. This screw is designed for applications requiring a lightweight yet robust fastening solution where electrical insulation and non-conductivity are paramount.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate M15 clearance hole or tapped thread for the 73mm length screw. 2. Hand-thread the polycarbonate hex head cap screw into the mating component until snug. 3. Apply torque using a standard hex drive socket, ensuring not to overtighten and exceed the material's yield strength.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-torquing the polycarbonate screw, leading to thread stripping or head deformation. | Use a torque wrench set to the recommended torque specification for polycarbonate fasteners of this size and application. |
| Using excessive force during installation, which can fracture the polycarbonate. | Thread the screw by hand initially, and only apply measured torque with a tool, respecting the material's properties. |
