Hexagon head screw cup commonly used in machinery, mainly for easy fastening and removal, not easy to slip angle and other advantages. Allen wrench is generally a 90 ° bend, bend one end of the long side of short, short side hit the screw when, holding the long side can save a lot of power and can better tighten the screws. long end partakers round (hexagon spheroidal) peace, round can be easily inserted into the screw holes very convenient disassemble, within the manufacturing cost hexagon hexagon much lower than, its advantages as well as conch (wrench force position) than the inner hexagon thin in some places can not replace Allen Further low cost, low power intensity , SHCS lower than the precision machinery used much less hex.
For hex head screws Cup comparison often used is Q235 wire rod, of course, there is the use of iron screws wire, wire for these screws can determine some of the characteristics hexagonal screws.
First, the first is to use stainless steel screws hardness is relatively high, but if it is the hardness of iron screws obviously sent a lot of this wire with the iron itself, there is a certain relationship. Iron texture itself belongs to a class of relatively soft, with stainless steel wire is simply no way ratio. However, in order to allow the screws to achieve iron hardness, for iron screw is generally used hardening heat treatment in the heat treatment process to ensure uniform heating screws, or not be able to make the hardness of the screw to meet the demand , it makes the screws easy Ends bent such that the inner will greatly increase the cost of production of hex head screws Cup. After the heat treatment will be able to iron hexagon socket head screw cup rose hardness, but due to wire problems in the quality of the above and still no way to stainless steel wire ratio.
For hex head screws have a cup to note is that in the process of using as much as possible not to let slip the screw head, otherwise it will lead to in the future is difficult to remove the screws.
