Zhuocheng Automotive nuts

Lock nut is a nut which widely used in machinery and other industries, the working principle of lock nut is to use the friction between the nut and the bolt for self-locking, in some important occasions we will take some anti-loosening measures to ensure the reliability of the nut locking,the higher interaction force between the lock nut and the meshing thread of the bolt,the effect will be better.Performance grade: carbon steel: grade 4/8/10/12, stainless steel A2-50/A4-70/80, etc,Standard:DIN; GB; JIS;ISO;BS;ANSI ,Material:Carbon steel,Stainless steel.

Generally, the lifting ring is made of Q235 material, and weldable low alloy steel can also be used. Through numerical control cutting or photoelectric cutting process, the lifting ring hole is made of drilling machine process. In the lifting industry, hooks and rings are common tools. The lifting ring series includes: long ring, pear ring, ring, child and mother ring, butterfly buckle and high-strength ring chain. The lifting ring is forged with high-quality alloy steel and heat treated for overall quenching and tempering. It can be connected and hoisted separately or made. 1. The main ring used to form chain slings, wire rope slings and fiber slings should adopt long rings, and circular rings can be used in other occasions.2. The connecting ring must be a long ring 3. It is not allowed to re-use the defective lifting lugs after repair welding.4. The lifting rings on the combined parts of lifting slings and riggings shall be inspected regularly according to the requirements of the combined parts.    

1. Removable anti-theft screws can be installed, including: inner Pentagon anti-theft screws, Torx anti-theft screws, Y-type anti-theft screws, outer triangle anti-theft screws, inner triangle anti-theft screws, two-point anti-theft screws, eccentric hole anti-theft screws, etc. 2. Removable anti-theft screws can be installed, including: slotted anti-theft screws (S-type anti-theft screws), carriage anti-theft screws, etc.Scope of application: anti theft screws have a wide range of applications, such as power facilities, railway facilities, highway facilities, oil field facilities, urban lighting street lamp facilities, lights, automobile tires and public fitness equipment. The product has superior performance and has been widely concerned and praised by all sectors of society.

Hexagon socket head screws are used for fastening. They are commonly used in machinery. They mainly have the advantages of easy fastening, disassembly and not easy to slide. They are divided into carbon steel and stainless steel according to material. This screw is often vibrated and shaken when installed on the machine, so some Allen screws may loosen. In order to avoid this phenomenon, we need to adopt some anti loosening treatment. 1 - add a suitable spring washer between the hexagon socket screw and the workpiece. 2. Drop resistant glue dispensing shall be made at the end of the thread of the inner hexagon screw. 3. If the socket head cap screw is used in a place that does not need to be disassembled, the screw can be welded in the installation position after the screw is installed

The shape of square nut is square so it also can be called square nut, the standard is DIN557 and material is divided into carbon steel and stainless steel. Square nut is one of the welding nuts which use high temperature to melt some metal welding in the middle of the two products play a fastening role, so the fastening effect of the connection will be better and not easy to loose, it also can be used with bolts together. Square nuts are mainly used in power engineering, traffic engineering, home building materials and other industries.Performance grade: carbon steel: grade 4/8/10/12, stainless steel A2-50/A4-70/80, etc, STANDARD:DIN; GB; JIS;ISO;BS;ANSI ,MATERIAL:Carbon steel,Stainless steel.Surface treatment:carbon steel surface treatment is generally boiled black, galvanized, non electrolytic zinc sheet coating, thick galvanized vzd and thick galvanizedZinc plus sealing (zsml), zinc nickel coating silver (znshl), zinc nickel coating black (zhbh)

The ball head bolt is an important automobile component that can simultaneously realize the up and down movement of the bracket suspension system and the rotation movement of the steering system at one point.In addition to friction, ball studs and ball stud seats also need to satisfy movement, durability, and reliability. There are two types of combinations of ball head bolts and ball head bolt seats: steel-on-steel and steel-on-plastic. Currently, cars mainly use the friction pair type of steel ball head bolts and plastic ball head bolt seats. Due to the repeated pressure and friction of the ball, the ball seat has problems such as poor lubrication, gradual failure, inability to turn correctly, and delayed turning. Therefore, the ball bearing surface must be wear-resistant and wear-resistant to ensure smooth operation and immediate steering. In addition to ensuring the wear resistance of the materials used for the balls and ball pin seats, special grease also needs to be added between the contact surfaces of the metal balls and ball pin seats. When poor lubrication occurs, abnormal wear and metal fatigue will occur between the ball and socket joints, resulting in looseness, uneven steering operation, increased noise, and shortened service life. In severe cases, it may directly endanger the driving safety of the car, such as being unable to turn correctly or turning slowly, etc.

Like automotive nuts and bolts, the most common screw is the hex screw. It is similar to the hex bolt, although it lacks a shank. Other types of screw fasteners used in the automotive industry include: Countersunk head screw: A machine screw with a tapered head that lies flat with the surface of a part.Grade 10.9 bolts: As these bolts are most often used in the automotive industry, they are also referred to as 'car bolts'. They are made of boron or carbon steel and have high tensile strength (1040 MPa).The worst mistake you can make with automotive fasteners is to assume that all are created equal. Even though two bolts might look identical with the same length, diameter and threads, they could have different strength grades, which suggest utterly different uses and locations.
