DIN912 Stock 304 / 316 Stainaless Steel Hexagon socket head cap screws ,allen screw
Hexagon head socket screw in the screw head is round, outside is dents hexagon among them, and the hexagonal screw is common edge into hexagonal screw head.Socket head screw driver looks like "7", ends with a hexagonal steel cutting and bending into a 90 - degree into a socket head screw wrench.
Hexagon Socket head screw press head division of cylinder head hex socket bolts, the most commonly used, and it has many types, according to the material of iron, which is carbon steel and stainless steel.Stainless steel hex bolts and adopts stainless steel SUS304, SUS202, etc material.Round head hex socket bolts, this also have called pan head hex socket bolts.Countersunk hex socket bolts, the head is flat, there is a socket head.There is a special kinds of national standard, called the headless socket head bolts.Or what we often call include screw, pay screws, set screws.Common term for this is the headless hex bolts, but the meaning is the same.Of course, there are some flowers form Allen wobbler bolt.The use of less, and basic it is hard to see in the market.
Stainless steel bolts / screw is made by metal and metal corrosion method mainly has four aspects, namely the nature of the material itself, the use of environment, data and environment of the interface, and improve the design of metal structures, if manufactured complete corrosion resistant alloy to stainless steel screws, unless there are special requirements, otherwise the concept of the economy, it is not really interstate or screw appearance corrosion environment factor is the complete isolation, also does not work in practice, can be very difficult.Metal structure design can be improved in a certain situation down to improve the effects of special circumstances, but most of the stainless steel screw design cannot fully corrected, and the maintenance work is not for rendering, so it couldn't handle basic problem, as long as the corrosion on the interface, i.e. appearance anti-corrosive treatment is currently the most widely used method.

Hexagon screws are widely used in machinery, mainly for fastening, disassembly, it is not easy to slip Angle and other advantages. Allen wrench is usually a 90 ° bend, bend at one end of the long and short, with a short side of the screw, holding a long side can save a lot of strength and better fastening screws. Long runs round head at one end (hexagonal cylindrical similar sphere) peace head, round head can easily inserted into the screw hole is very convenient disassembly, the outside hexagonal manufacturing costs less than Allen, its advantages and screw head (wrench stress location) thinner than Allen screw, in some places is not Allen can replace. Also the cost is low, dynamic strength is small, low accuracy of machine adopt socket head screw is much less than the outer hexagon.
