Customized doorway with long hexagon socket screws

Zinc Plated Hex Bolts, external hexagonal long screws, long bolts, hexagon socket long screws, long screws, also called long bolts, can only be manufactured under advanced equipment and mature technology.Long screws are common in machinery, electrical appliances and buildings, etc., generally metal Manufactured, in a cylindrical shape, with concave and convex grooves on the surface, such as an inclined surface surrounding the side of the screw, so that the long screw can lock the screw cap or other objects tightly. The top of the long screw has a larger diameter, which can be round inner hexagon or equal outer hexagon, so that tools such as a screwdriver or a wrench can turn the long screw.

The protruding top also prevents the long screws from drilling too deep to penetrate the material, and increases the pressure of the long screws on the material. Hexagon socket long screws use: Hexagon socket screws are often used in machinery, mainly for easy fastening, disassembly, not easy to slip corners and other advantages. Allen wrenches generally have a 90° turn. The bent end is long and short. When using the short side to screw the screw, holding the long side can save a lot of force and can better tighten the screw. The long end has The round head (hexagonal cylinder is similar to the sphere) and flat head.

The round head can be easily slanted and disassembled. It is inconvenient to install some parts of the wrench. The manufacturing cost of the outer hexagon is much lower than that of the inner hexagon. Its advantages are also The screw head (the force position of the wrench) is thinner than the inner hexagon, and some places are not replaceable by the inner hexagon. In addition, the machine with low cost, low power strength, and low precision requires much less inner hexagon screws than the outer hexagon.
