Summary of information:We have more than ten years of experience in screw industry production, the main products are: pattern washers, DIN7991 ...

For hexagonal nuts, the commonly used standards are: GB52, GB6170, GB6172 and DIN934. The main differences between them are: the thickness of GB6170 is thicker than that of GB52, GB6172 and DIN934, commonly known as thick nuts. The other is the difference between the opposite sides, the opposite sides of DIN934, GB6170 and GB6172 in the M8 nut series are 13MM smaller than the opposite side 14MM of GB52, and the opposite sides of M10 nuts, DIN934 and GB52 are 17MM. The opposite side of GB6170 and GB6172 should be 1MM larger, M12 nut, DIN934, GB52's opposite side is 19MM larger than GB6170 and GB6172's opposite side 18MM is 1MM larger. For M14 nuts, the opposite side of DIN934 and GB52 is 22MM, which is 1MM larger than the opposite side of GB6170 and GB6172, which is 21MM. The other is the M22 nut. The opposite side of DIN934 and GB52 is 32MM, which is 2MM smaller than the opposite side of GB6170 and GB6172, which is 34MM. (Besides the thickness of GB6170 and GB6172 are the same, the width of the opposite side is exactly the same) The rest of the specifications can be used in general without considering the thickness.

Guangdong Yueluo Hardware Industry Co., Ltd. relates to a connecting piece, especially a wood screw used for fixing on non-rigid materials such as wood or plastic. Guangdong Yueluo Hardware Industry Co., Ltd. has a threaded part with a taper angle and a screw head. The head of the screw can be countersunk, hemispherical, or other shapes. As for the grooves for screwing, the grooves can be straight-line grooves, concave cross grooves, or grooves of other shapes.

shaft retaining ring installation tool and an installation method thereof relate to an assembly tool and an installation method thereof, comprising a pressing cylinder and a taper sleeve. The maximum diameter of the tapered end is slightly smaller than the inner diameter of the circular straight hole of the pressing cylinder, and the lower end of the tapered sleeve has a positioning structure matched with the shaft of the shaft retaining ring to be installed. The method includes the following: place the taper sleeve on one end of the shaft where the shaft retaining ring is to be installed and position it well, then place the shaft retaining ring on the tapered end of the taper sleeve, and finally press down the pressure cylinder to make the shaft Use the retaining ring to slide down the conical surface of the taper sleeve to the shaft to be installed with the retaining ring for the shaft, and finally get stuck in the groove of the shaft. Yueluo does not need to open the retaining ring for the shaft, which reduces the operation force and labor intensity. The operation method is simple, the structure is simple and reliable, the cost is low, and it is easy to popularize and use.

304L stainless steel cold pier line, 304 stainless steel cold pier line, 310 stainless steel cold pier line, 303 stainless steel cold pier line, 302 stainless steel cold pier line, 301 stainless steel cold pier line, 202 stainless steel cold pier line, 201 stainless steel cold pier line, 410 stainless steel Cold pier line, 420 stainless steel cold pier line, 430 stainless steel cold pier line, 316L stainless steel cold pier line: 316 stainless steel contains molybdenum and low carbon content, and its resistance to pitting corrosion in marine and chemical industry environments is much better than 304 Stainless steel! (316L low carbon, 316N nitrogen high strength and high strength, 316F stainless steel with high sulfur content, easy to cut stainless steel [1]. 304L stainless steel cold pier wire: as a low carbon 304 steel, in general, the corrosion resistance is the same as 304. Similar, but after welding or after stress relief, its resistance to grain boundary corrosion is excellent, and it can maintain good corrosion resistance without heat treatment. 304 stainless steel cold pier wire: has good corrosion resistance, heat resistance High temperature resistance, low temperature strength and mechanical properties, good thermal processability such as stamping and bending, no heat treatment hardening phenomenon. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (use temperature -196°C-700° C) 310 stainless steel cold pier wire: The main features are: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are average. 303 stainless steel cold pier wire: By adding a small amount of sulfur and phosphorus, it is easier to cut than 304, Other properties are similar to 304. 302 stainless steel cold pier wire: 302 stainless steel bar is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. The details are as follows: handicrafts, bearings, slippery, medical equipment, electrical appliances, etc. Features: 302 stainless steel The ball is austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC≤28, and has good rust and corrosion resistance. 301 stainless steel cold pier wire: good ductility, used for forming products. Machining makes it harden quickly. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel. 202 stainless steel cold pier wire: belongs to chromium-nickel-manganese austenitic stainless steel, and its performance is better than 201 stainless steel cold pier wire Shenzhen Global Stainless Steel Cold Pier Wire 201 Stainless Steel Cold Pier Wire: It belongs to chromium-nickel-manganese austenitic stainless steel, with low magnetic properties. 410 stainless steel cold pier wire: belongs to martensitic (high-strength chromium steel), with good wear resistance and corrosion resistance Poor performance. 420 stainless steel cold pier wire: cutting tool grade martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. It is also used for surgical knives and can be made very bright. 430 stainless steel cold pier wire: Ferritic stainless steel, decorative, e.g. for car accessories. Good formability, but poor temperature and corrosion resistance

Screw (English a screw) refers to the parts used in construction machinery. It is a kind of threaded parts with sharp ends such as nails, small cylindrical or conical metal rods, with grooved or dimpled heads, and used alone. . The detection of the screw should start from the wire of the screw. The quality of the precision screw is directly related to the wire that produces the screw. A good screw wire will open the screws more beautifully. What screw head burst, what thread is bad. Good screw wires generally do not find this situation.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: small bolts, iron black pins, specializing in the production of nuts, thickened plastic gaskets and other products, we can provide you with suitable fastener solutions for you Program.
