There are countless standard parts on the market, if you want to buy standard screws, there will be standard screws. Let's talk about screw standard parts first. Screws are usually called in the industry. Screws usually include screws and bolts. There are many standards in the general market: DIN912 (GB70-85) hexagon socket screws. Its minimum size can reach M2 (the screw diameter and thread length are not limited). For example: M2.5 M3 M4 M5 M6 M8 M10 M12 M14, etc. (the length is not limited).   What is the specification of the standard screw? It consists of the thread (the distance between the thread and the thread), the diameter of the threaded rod and the length of the threaded rod of the screw (excluding the head). Let us take the above standard part data as an example. For example: the minimum specification M2, its professional standard name is: M2-0.4X5 (0.4 is the pitch, M2 is the length of the screw, and 5 is the diameter of the screw). The materials of general standard pa

The template fastener has a simple structure and is easy to install. Workers using square column fasteners can reinforce the column formwork within 20 minutes. Once launched, it was welcomed by most construction workers. Let me give you a detailed introduction to template fasteners. 1. Formwork fastener is a new type of fastener used to construct square columns in building construction. It is suitable for the quick reinforcement of the square column after the custom square column template and the ordinary template template. Its novel structure and installation method are obviously different from traditional frame pipe and channel steel reinforcement. 2. Formwork fastener is a specially customized supporting fixture for fixing square column formwork. Its appearance consists of a galvanized card plate corresponding to four elbows. One end of the card board is arranged in a curved structure, and each card board is provided with a plurality of fixing holes with equal intervals along the le

 Metric Stainless Screws - Some Interesting Facts Metric stainless steel screws have been an important engineering material for years - very useful most especially in aviation, construction, and other industries. What's the big deal about this kind of material? Why is it popular in the industry? When do you need to choose metric stainless screws for your project? These are important questions we need to address. And some interesting facts below can help us find the answers. An ordinary metal like carbon steel screw is prone to rusting. Exposure of this material to oxygen would lead to oxidation - a chemical reaction between the material and the atmosphere. And, it is important to note that the more corrosive your environment, the faster oxidation process would take place. Seaside for instance is more corrosive - metals corrode more quickly when near the sea. Although industries used to be satisfied with carbon steel for centuries, the fast-paced environment and the tough competitio

 Types Of Screw Fasteners - Using The Right Type Of Screws Well for a lot of tasks we may well find that a nail is the ideal fixing, however when it comes to fasteners then you would be hard pushed to find anything better than a screw. Investing In The Best Tools The first thing I would say is that when it comes to using screws, buy an electric screwdriver. Invest in a good one as it will pay for itself many times over, in fact as DIY tools go it is most likely to be the best investment you have ever made. You may find yourself spending a £100 on one and then only using it twice in three months, but then you will end up doing a big DIY job and wish you had bought two batteries. When it comes to using screws as fastenings, an electric screwdriver is a Godsend. Screws can be used to fasten just about any material together other than fastening something to bricks or concrete, in which case you will need a specialist fixing such as a raw plug, to screw in to. You can buy screws from tiny b

Metric fastener is a very important engineering material, which has been used in many applications in different fields. Many industries use various types of Metric Fasteners, such as construction, wood processing, mobile and aerospace, and electronic equipment production. However, in this particular content, I will introduce metric thread forming screws in particular. These are screws used to form material or base material around the hole until they are wrapped around the thread. As opposed to other metric screws, they do not remove any parts from the joint. How do self tapping screws work? In layman's terms, screw forming screws force the substrate or material to fit into its thread. The process is similar to self tapping screws (self tapping screws remove debris from the material), but they deform the substrate only by bending the substrate to the mating position without removing any of the joints. application area Metals or metallic materials - they can be used in a variety of m

What is hardware? It is a general term which refers to metal tools used in the building and furniture. There are a lot of hardware products. They can be grouped into big hardware and small hardware. The former refers to steel materials, such as steel plate, steel bar, channel iron, flat iron. The later often refers to the following items, such as construction hardware, tin plate, iron wire, household hardware, and tools. According to its property and function, the hardware also can be grouped into eight classifications, namely steel material, non-iron metal material, mechanical parts, transmission equipment, auxiliary tool, work tool, construction hardware and household hardware. Owing to the limited space and time, the article will mainly introduce the small hardware. It has a lot of varieties and specifications. It plays a very important role in the room decoration. Only through choosing the good hardware components can people use the decorating material safely and conveniently. At p

Many times, the type of screw you decide to use will depend on the material of the screw. Below are a few different types of these specific fasteners and fixtures, and the materials they are most suitable for. Round head screws-Although self-tapping screws are usually used for hard materials, if you need to use thinner materials, round head screws may be the best choice. These are the most common screw types. Many times, this kind of screw is used in combination with a washer. Pan head-If you are using heavy materials, you should consider using a pan head. They are oval in shape with a tapered base, suitable for hard materials. Flat head-For those "home assembly" type furniture, you may want to consider using flat head tapping screws. Generally, they last longer than the nails and bolts given to you in the home assembly package. Phillips Heads-Are you working on plasterboard or timber projects? The crosshead may be your best choice. This type of head provides more control and
