Made from black nylon 66, these cap nuts are chemical resistant, nonconductive, and lightweight. Also known as acorn nuts, they have a smooth rounded head that covers and protects threads while providing a finished appearance

Acid resistance, alkali resistance, fire rating, insulation performance.

1. Compared with ordinary metal cap nuts, the biggest advantage of plastic cap nuts is that he has good insulating properties, non-conductive.

2. In addition, because of non-metallic manufacturing, the current or other electrical signals will not produce eddy currents under the influence of signal interference; its anti-interference is suitable for communication and other industries.

3. Plastic black nylon cap nuts' acid and alkali resistance is better, the best PVDF cap nuts followed by polypropylene, both have strong acid and alkali resistance, and nylon cap nuts compared to the first two, resistance to strong acid and alkali performance is relatively poor, so in the electroplating industry in some of the strong acid and alkali environments, the plastic cap nuts, especially the PVDF cap nuts have a very wide range of applications!

Disadvantages

1. The biggest defect of plastic black nylon cap nuts is that the torsion and strength of ordinary nylon cap nuts are not as strong as ordinary metal nuts, and the torsion is too large with the possibility of slipping teeth or head fracture.

2. Due to different plastic molding shrinkage reasons, temperature and humidity changes, molding cycle length, and other reasons, plastic cap nuts size error tolerance. In addition, due to the soft material of ordinary plastic, can not use the conventional ring gauge measurement method.
