Popular science small knowledge of CD pattern screw

Publish time: 18 Aug 21

CD pattern screws in the sun, along the middle point to emit a number of rays around (like our common CD in the sun irradiation effect), in fact, this is machining along the middle of the concave and convex texture formation. CD pattern screw also has many kinds of names, smooth grain, colorful grain, sun grain, although the name is not the same, but it actually refers to the same production
Satin brushed screw has so many head types,such as slotted, cross drive, five slot, hexagonal socket drive, plum groove.
Generally, CD texture spacing is between 0.02-0.20mm. Most of the screws are made of stainless steel 302 and 410(there is also carbon steel and aluminum to do surface treatment), the effect of other materials is not very good. General material requirements of plastic medium, plastic too low, turning texture when there is brittle crack extension, surface roughness is not beautiful, plastic too high material wilting processing will occur adhesive tape, just like stick knife processing is not beautiful, need to be processed after processing CD pattern.
In terms of assembly efficiency, stainless steel 302 is not as high as 410 assembly efficiency, because stainless steel 302 belongs to austenitic stainless steel, is weak magnetic, installation tools are inconvenient to absorb. The 410 stainless steel is ferrite stainless steel, magnetic, easy to install tools.
In general, like in many decorative crafts and some mobile phone electronic products can see the figure of CD pattern screws, beautiful appearance, but also with added value, by everyone's love. Suzhou Anzhikou Hardware Technology Co., LTD. Mainly produces CD grain screws, precision screws, anti-loose screws, non-standard custom screws, if necessary, you are welcome to inquire!
