Socket head cap screws are also called Allen head screws, socket screws, which are threaded screws with a cylindrical head or hexagon drive hole.hex socket screws are driven by using a They are driven with socket wrench or Allen hex key, types include button head, flange button head, flat head, socket cap, etc.

Hex bolts feature six-sided hexagonal-shaped heads which are a type of thread bolt, they can be either full-threaded or partially threaded(with a clear shank along part of the body). Hex had bolts primarily used for head duty fixing and fastening applications including within construction projects, during the erection, repair, and maintenance of buildings, bridges, and road infrastructure, machinery assemblies, woodworking tasks, and engineering applications, also vehicles and the automotive industry

The difference between hexagon socket bolts and hexagon bolts

  1. For appearance: The hex socket cap screws are with a drive hole, and the hex bolts are with six-sided hexagonal-shaped heads.
  2. Tools to be used: The two kinds of screws are assembled and disassembled with different tools. The two kinds of screws with the same material and the same thread have the same load capacity. The selection is mainly based on the requirements of the installation position for the screw head. For example, if you need to use For countersunk head screws, it is much more convenient to use hexagon socket screws to fasten, but the depth of the counterbore that needs to accommodate the screw head is much larger, and a special hexagon wrench is required, That means hex socket cap screws will are more trouble than hex bolts because which can deal with different sizes than ordinary adjustable wrenches, so it is necessary to choose to use a hexagonal head or hexagonal head according to the specific situation.
  3. The socket screws take up much less space, and socket cap screws can be installed in a deeper position during installation, while the hex bolt installation (including fastening) requires a lot of space.
  4. The head of the hexagon socket bolt can sink into the part without being exposed, the overall size is reduced, the appearance is beautiful, and it does not hinder other parts.
  5. The manufacturing cost of the hex bolts is much lower than that of the inner hexagon. Its advantage is that the screw head (where the wrench is stressed) is thinner than the socket head cap screws, and some places cannot be replaced by the socket cap screws. In addition, machines with low cost, and low precision requirements use much fewer socket head screws than hexagonal bolts.
