railfastening

  They are made of high strength steel. High-strength bolts are used for the connection of bridges, railways, high-pressure and ultra-high-pressure equipment, high-strength bolts in ultra-high-pressure equipment, or greater pre-stressing in order to keep the container sealed. The   Bridge Bolt   connection has the advantages of simple structure, good mechanical properties, mobility, and fatigue resistance. Surface treatment: Hot-dip galvanizing or electro-galvanizing is the standard surface treatment for such products, and other surface treatment requirements can be tailored to actual requirements. We welcome you to consult our existing products and customize your products according to the drawings.

  Railway Bolts   are commonly used at rail joints and their dimensions can vary depending on the requirements of the different parts of the rail. Rail bolts of suitable diameter and length are generally determined by applicable rail standards. It has many classifications, such as round oval necks, diamond neck rail bolts, and F50-008 standard rail bolts, Russian standard rail bolts and other special requirements for rail bolts. According to the relevant railway standards, at least two sets of bolts are required for each rail joint to be fastened, each bolt is tightened to a torque of approximately 400 ft., and the product itself needs to be between 25,000 and 30,000 lbs. A) Bolts must be properly sized according to the standard and tightened in place. B) Bolts must use spring washers and nuts. C) The nut used with the bolt can be selectively mounted on the inside or outside of the rail. D) When the bolt and the  Fish Plate  are removed from the rail, the contact sur...

  Railway Fastening System   is a set of fastening system for fastening the rail to the sleeper. It is usually composed of anti-climbing device, iron pad, mounting seat, fasteners such as spikes, bolts, spring bars, etc. The most important consideration for the system as a rail fastener is safety. This safety is not compromised. Different Fastening Systems have been evolving with the development of railways. There are basically pad and spike fastener systems on the sleeper, E-type spring fastener system, gusset fastener system, SKL fastener system and so on. In addition to the individual components in the production of rail fastener systems, TAICANG ZHONGBO RAILWAY FASTENING also manufactures and offers a wide range of fastener systems, which is one of the strengths of our plant. As a  Railway Fastening System Exporter , we not only manufacture these complete fastener systems for ordinary railway, subway and high-speed railway projects at home and abroad, but also design ...

  Bolts are common mechanical parts and are often used in many places. It is a type of fastener consisting of two parts, the head and the screw. It needs to be used with a nut. It is mainly used to fasten and connect two parts with through holes. Maybe you don't know anything about the grade of the bolt.   Hex Bolt China Supplier   will introduce you to the bolt material and grade. What is the grade and material of the bolt? The bolt grade refers to the bolt grade of 4.8, 8.8, 10.9 and so on. The material refers to the material used for the bolt, such as 45# steel, 35CrMo steel, and 304 stainless steel. The grade and material of the bolt are related to each other. Low carbon steel can only produce low-strength grade bolts, carbon steel can produce medium-strength grade bolts, and alloy steel can produce high-strength grade bolts. Some bolt grades specify the corresponding chemical composition and mechanical properties, and the materials are specified. So, how to distingui...

  It should be no stranger to talk about T Bolt. The application of T Bolt in life is not uncommon. Let's take a look at it with the   Rail Fishplate Manufacturer . A nut that is screwed together with a bolt or a screw to serve as a fastening part. Depending on the material used in the manufacturing machine, the same component can be divided into several categories including carbon steel. , stainless steel, non-ferrous metals, etc.  T Bolt  is a nut that looks like T. T Bolt is not only easy to install and unload, but also easy to install parts in any position, which can greatly improve labor productivity. This is why t-nuts can be widely used in T-slots of various milling machines.
