Durable M18 Carbon Steel Hex Bolt With Zinc Plated Surface Treatment
M18 Carbon Steel Hex Bolt Grade 8.8 DIN 961 Black Oxide Full Thread,this item is one of our main products.Other names of hexagonal bolts are:Hexagon head bolt (rough), light hexagonal bolt (refined), hexagon head screw, hair hexagon head bolt, black iron screw.In conjunction with the nut, the thread connection method is used to connect the two parts together into a whole. The characteristic of this connection is detachable. If the nut is screwed down, the two parts can be separated. The product level is C, B and A.Steel structure connection bolt performance are rated 3.6, 4.6, 3.6, 4.6, 6.8, 8.8, 9.8, 10.9, 12.9, and so on more than 10 levels, including a magnitude of 8.8 and above the bolt is made of low carbon alloy steel and medium carbon steel and the heat treatment (quenching and tempering), known as high strength bolts, the rest of the known as regular hexagonal bolt.Bolt performance rating label consists of two parts Numbers respectively represent the nominal tensile strength value of bolt material ratio and flexion and extension.
Common tools for driving screws include screwdrivers and wrenches. The head is usually larger than the body of the screw, which keeps the screw from being driven deeper than the length of the screw and to provide a bearing surface. There are exceptions; for instance, carriage bolts have a domed head that is not designed to be driven; set screws often have a head smaller than the outer diameter of the screw; J-bolts have a J-shaped head which is not designed to be driven, but rather is usually sunk into concrete allowing it to be used as an anchor bolt. The cylindrical portion of the screw from the underside of the head to the tip is known as the shank; it may be fully threaded or partially threaded.
