Purpose-built for heavy-duty applications, this M20x122mm Hex Head Cap Screw is manufactured from high-performance polycarbonate, offering superior tensile strength and excellent resistance to impact, abrasion, and chemical corrosion. With a head width of 16mm, it provides ample surface area for torque application and load distribution. The robust polycarbonate material ensures non-conductivity, making it ideal for electrical enclosures, marine hardware, and corrosive industrial settings where traditional metal fasteners may degrade or pose a safety hazard. Its dimensional stability ensures reliable performance under extreme temperature fluctuations.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threads are clean and free from debris. 2. Hand-tighten the screw initially to prevent cross-threading. 3. Use an appropriate wrench or socket to tighten the screw to the specified torque, avoiding overtightening which can damage the polycarbonate.
