Made from nylon 6/6, 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 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 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.
Product Specification
Plastic nylon cap nut is a fastener with a large contact area and strong anti-loosening ability, which has the advantages of simple installation, good sealing, dustproof, and isolation. Its main function is to connect two or more objects together through threads to form a whole. Plastic nylon cap nuts are usually used in automobiles, ships, electrical equipment, construction machinery, electric control boxes, and other fields. Cap nut is a common fastener, its main role is to fix and connect various metal parts, such as bolts, screws, etc., to ensure that they will not loosen or fall off in the process of use. Metal carbon steel, stainless steel, and copper cap nuts are widely used in machinery, equipment, construction, and other fields.
Cap nut's shape is similar to ordinary nuts, but it has a raised part on the top that can be matched with various shapes of metal parts so as to realize the purpose of fixing and connecting.
Cap nuts can be categorized into various types according to their shape, of which the common ones are hexagonal and square. According to their use, cap nuts can be divided into ordinary cap nuts, anti-loosening cap nuts, and so on. Ordinary cap nuts are suitable for general fixing and connection; anti-loosening cap nuts have an anti-loosening function applicable to the need to prevent the bolt from loosening the occasions; the cap nut has a higher mechanical strength, applicable to the need to withstand a greater load of the occasion.
The selection of plastic nylon cap nuts:
1. Select the corresponding cap nut according to the bolt specification.
2. Select the appropriate material for the cap nut according to the application environment.
3. Pay attention to the actual torque of the cap nut, do not use too much or too little torque.
