Galvanized Hex Bolts High Quality DIN933 Carbon Steel Zinc Plated M8 M10 M12
Product description:
The first bolts had square heads, formed by foriging . These are still found, although much more common today is the hexagonal head. These are held and turned by a spanner or wrench, of which there are many forms. Most are held from the side, some from in-line with the bolt. Other bolts have T-heads and slotted heads.
Many screws use a screwdriver head fitting, rather than an external wrench. Screwdrivers are applied in-line with the fastener, rather than from the side. These are smaller than most wrench heads and cannot usually apply the same amount of torque . It is sometimes assumed that screwdriver heads imply a screw and wrenches imply a bolt, although this is incorrect. Coach screws are large square-headed screws with a tapered wood screw thread, used for attaching ironwork to timber.
Bolts use a wide variety of head designs, as do screws. These are designed to engage with the tool used to tighten them. Some bolt heads instead lock the bolt in place, so that it does not move and a tool is only needed for the nut end.
Common bolt heads include hex, slotted hex washer, and socket cap.
Head designs that overlap both are the Allen or Torx heads; hexagonal or splined sockets. These modern designs span a large range of sizes and can carry a considerable torque.
The galvanized hex bolt is a kind of fastener consisting of two parts of the head and the screw (the cylinder with the external thread). It needs to be fitted with the nut for fastening and connecting two parts with through holes. The bolts are divided into iron bolts and stainless steel bolts according to the material.
