A high-performance industrial component, this M18 x 134mm hex head cap screw boasts a nominal diameter of M18 and a total length of 134mm. The head width measures 24mm, ensuring compatibility with standard tooling. Manufactured from high-impact polycarbonate, it offers excellent tensile strength, chemical resistance to many common solvents and acids, and superior dielectric properties. Its lightweight nature and non-magnetic characteristics make it ideal for environments where metal fasteners are unsuitable due to corrosion, conductivity, or interference concerns.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating surfaces are clean and free from debris. 2. Insert the M18 polycarbonate hex head cap screw into the pre-drilled or tapped hole. 3. Tighten using a socket wrench or appropriately sized hex key, applying torque gradually to avoid overstressing the polycarbonate material.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Applying excessive torque, leading to thread stripping or head fracture. | Use a torque wrench and adhere to recommended torque values for polycarbonate fasteners, or use a hand-tightening approach with a final snug fit. |
| Using metal washers that can cause galvanic corrosion or damage the polycarbonate surface. | Utilize compatible polycarbonate or nylon washers to maintain material integrity and prevent damage. |
