Features of Stainless Steel Flat Head Screws Of Black Flat Hand Thumb With High Precision
The flat head can be divided into a full countersunk head and a half countersunk head. The flat head cone angle generally has 3 types of countersunk heads: 900, 1000 and 1200. In the Russian standard system, it is customary to use 900 and 1200 flat heads. The 1200 flat head is mainly used for thin-walled structures (such as thin skins), but because the thickness of the head is thin, the depth of the screwing groove is not easy to control, the groove is too shallow, the screwing performance is too poor, and it is easy to "slip" when installing and disassembling bolts. ; The groove is too deep, it will weaken the nail head strength, easy to turn around. In the ISO/TC2 standard system, there are only 900 flat heads, while in the ISO/TC20/SC4 standard system, there are only 1000 flat heads and 1000 small flat heads. Small flat head refers to the type with reduced head height. It is used for thin-walled structures of aerospace vehicles. Due to the characteristics of the flat head bolt structure, the head strength is generally lower than the screw strength or thread strength. When flat head bolts are subjected to tensile failure test, The head of the bolt is usually destroyed first.
