Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this M11x70mm hex head cap screw is constructed from high-performance polycarbonate, offering excellent chemical resistance, high impact strength (Izod notch), and a non-conductive dielectric constant. The M11 thread provides robust mechanical engagement, while the 70mm length allows for secure fastening in thicker materials. The 10mm head width ensures compatibility with standard tooling. Its inherent UV stability and wide operating temperature range make it suitable for both indoor and outdoor applications, outperforming many traditional metal fasteners in specific corrosive and electrolytic environments.

Installation Procedure

1. Select the appropriate mating hardware (nut or tapped hole) compatible with M11 threading. 2. Insert the cap screw through the assembled components, ensuring proper alignment. 3. Tighten the cap screw using a suitable wrench on the hex head until the desired clamping force is achieved, avoiding over-tightening which could damage the polycarbonate material.
