Stainless steel cylindrical head hexagonal screws, also called stainless steel cylindrical head hexagonal bolts, is a kind of hexagonal hole type screws. It is widely used in daily life, and the following Aozhan fastener manufacturer will take you to understand.
Stainless steel socket head screws can be divided into: stainless steel cheese head socket head screws, stainless steel pan head socket head screws, stainless steel countersunk head socket head screws, stainless steel socket head shoulder screws. Cylindrical head socket head screws have a knurled head and not knurled, knurled stainless steel cylindrical head socket head screws production raw materials are mostly seen SUS304 stainless steel material (also known as 304 hexagonal screws) or SUS316 stainless steel material (also known as 316 hexagonal screws), nickel content reached eight nickel above, the material grade are A2-70 and A4-70. head without knurled cylindrical head The hexagonal head without knurling is generally made of SUS201 stainless steel material with relatively low nickel content.
Stainless steel socket head cap screws are mainly used in mechanical equipment, such as: chemical machinery and equipment, ships, power distribution equipment and other outdoor places. Stainless steel socket head cap screws are divided into stainless steel socket head cap screws with full teeth and stainless steel socket head cap screws with half teeth, stainless steel socket head cap screws with full teeth are more common, stainless steel socket head cap screws with half teeth are generally used in export equipment more.
Stainless steel socket head cap screws of high quality is mainly conducive to tightening and disassembly, not easy to slip teeth, easy to install, neat appearance, etc.. Its main disadvantage is that the production cost is higher than the external hexagonal screws, and in some places the installation is not convenient to use a wrench.
Stainless steel cylindrical head socket head screws are generally SUS201, SUS304, SUS316 materials manufactured into the simple environment can be determined by stainless steel cylindrical head socket head screws color and magnetic to determine its material, SUS201 stainless steel socket head screws without knurling, the surface is dark and bright, containing a relatively high with magnetic; SUS304 stainless steel socket head screws With knurling, bright surface, with a slight magnetic, the head generally has A2-70 label and manufacturer’s trademark or logo; SUS316 stainless steel socket head screws also with knurling, light gray glossy surface, generally no magnetic or slightly magnetic, the head generally has A4-70 label and manufacturer’s trademark or logo.
The above is a brief explanation of the knowledge of stainless steel hexagonal socket head screws, I hope it will be helpful to you.
