Titanium Screws And Stainless Steel Screws Which Is Better

Titanium screws  are often used in high-end products in recent years because of their characteristics. However, stainless steel screws are used more frequently in our daily lives. Today we talk titanium screw and stainless steel screw in the end which is good. Generally, titanium screws are used in pure titanium TA2 and titanium alloy TC4. The raw material of the titanium screw is relatively expensive compared to the raw material of the stainless steel, and the screw is also very beautiful and very light. Titanium is resistant to acid and alkali corrosion, so ti screw are generally more expensive. As a raw material for the production of titanium screw, titanium is a highly active metal. Compared with stainless steel, titanium screw have better flexibility and oxidation resistance. Many screws used in high-end products and medical equipment are usually titanium screw. Because ti screw have non-toxic properties, they do not harm the human body. Ordinary stainless steel screws have...

Does The Aluminum Flat Head Machine Screws Need A Flat And Spring Washer?

Normally, the  aluminum flat head machine screws  do not require the use of a washer. The flat head phillips screw is a type of screw that has a flat head and is countersunk or semi-recessed.

To understand this problem, let us first understand the role of flat washers and spring washers! Flat washer: Increase the contact area between the screw and the machine. Eliminate damage to the machine surface when the spring washer is unloaded. When using, it must be a flat washer after the spring washer, the flat washer is next to the surface of the machine, and the spring washer is between the flat washer and the nut. The flat washer is to increase the force area of the screw. The function of the spring washer is to prevent the screw from loosening and play a certain buffer protection when the force is...

Slotted Screw? Do You Know Its Production Process?

The processing of slotted is divided into three kinds, one is the mold forming directly, one is the milling machine forming or the automatic cutting machine is formed. It depends on the actual product requirements to decide which process way to use. Mold direct molding, processing speed is very fast, high efficiency, the cost is much cheaper compared to the lathe cost, but there is a small malpractice, there will be a little bit of “eight” shape on both sides of the slot, if only to meet the use of a word lock tight, this quality requirement is no problem. The milling machine is very slow and purely manual. It is generally suitable for products that are not large in size and require smooth and smooth characters. Automatic slotting machine molding, although the speed can not be compared with...

What Are The Characteristics Of Stainless Screws?

Stainless screws  are usually steel screws that have the ability to withstand the corrosive effects of air, water, acids, alkali salts or other media. Stainless steel screws are generally not prone to rust and corrosion. Can be used in environmental protection equipment, medical equipment, communication equipment and other fields. Stainless steel focuses on rust and acid resistance depending on the composition of the alloy. Although some steels have rust properties, they are not necessarily acid-resistant, and acid-resistant steels usually have rust properties. In people’s daily life, stainless steel is often referred to as austenitic stainless steel. The stainless steel screws we use are mainly made of austenitic 302, 304, 316 and “low nickel” 201. Stainless screw s  selection principle: The choice of stainless steel materials is mainly considered from the following five aspects.

Long screws , as the name implies, are even longer than ordinary screws. What are the materials of the  long sc rews ? There are mainly three materials: stainless steel, carbon steel and aluminum, among which there are relatively more stainless steel.

Long Brass Screw – Shenzhen Shi Shi Tong Screw Factory

Long brass screw  is also a long screw. There are two kinds, one is made of copper material, and one is surface treatment is copper plating, this premise is that the material is carbon steel, because carbon steel material plating is not easy to fade, if it is stainless steel, it is suggested to maintain the color, not electroplating. Let’s start with long screws made of copper material. Copper wire is divided into H70 brass screw wire, imported brass screw wire, and H68 brass screw wire. These screw wires have excellent plasticity (the best in brass) and high strength, good machinability, easy to weld, very stable to general corrosion, but prone to corrosion cracking.It is the most widely used variety of common brass.Copper wire itself is more expensive, so it will be more expensive to make long screws, which is not difficult to understand the reason for the high price of copper screws; To make long screws with copper wire, domestic or less.

When the long pass is long, we need to grind the threaded part or the cnc short to reach the desired length. Of course, when selecting the required screw, the first thing to be determined is the diameter of the thread and the length of the thread. Then determi...
