Product Specification

DIN985 Nylon Locking Nut,Carbon Steel,Coarse Threaded ,Zinc Plated

1. Product Description

Nylon Lock Nut - Insert nylon rubber ring in hexagonal surface to prevent loosening thread structure and use in strong power machinery.

General nut in the use of the process due to vibration and other reasons will be loose, in order to prevent this phenomenon, so the invention of self-locking nut. Self-Locking nut Its function is mainly to prevent loose, anti-vibration. For special occasions. Its working principle is usually by friction self-locking. The type of self-locking nut, which is classified by function, has a nylon ring, a neck, and a metal loosening device. They all belong to the effective torque type of anti-pine nut self-locking nut is generally rely on friction, the principle is through the embossing teeth into the sheet metal preset hole, the general square hole aperture slightly smaller than the rivet nut. The use of nuts and locking mechanism connected, when tightening the nut, locking mechanism lock ruler body, ruler frame can not be free to move, to achieve the purpose of locking; When the nut is loosened, the locking mechanism is removed and the ruler is moved along the ruler.

High-strength self-locking nut is a classification of self-locking nut with high strength and strong reliability. Mainly the introduction of European technology as a prerequisite for road-building machinery, mining machinery, vibration machinery and equipment, domestic production of such products are very few manufacturers

3. Application

High-strength self-locking nut for marine and bridge, it can convert friction into the expansion force between bolt and groove nut to achieve excellent self-locking effect. There are two slots in the upper part of the ESL nut, when the nut is tightened on the bolt, the thread of the bolt will be screwed into the narrow groove of the Nut cross section, and the thread is gradually locked by the nut side wall to achieve the self-locking function. The exquisite production process can keep the torque type of the locking element consistent, products are generally used in railway casting, rail transit, transmission systems, mining equipment, highways, military, oil production machinery, automotive industry, public facilities, subways, engines, construction machinery, aerospace, drilling equipment, bridges, generators, agricultural machinery, shipbuilding industry , metallurgical equipment, trains, compressors, medical machinery, signal systems, wind power generation.
