Hexagon head bolts are divided into hexagonal bolts and hexagonal screws.
Introduction
Hexagon head screws Hex cap screw and large hex bolts Hex bolt As the name suggests for the hexagonal male screw fasteners, designed to use the wrench to rotate. In accordance with the ASME B18.2.1 standard, the hex head screw (Hex cap screw) than the general hexagonal bolt (Hex bolt) head height and rod length tolerance is small, so ASME B18.2.1 hexagonal screws suitable for installation in all hex bolts can be used Place, also contains large hex bolts too large and can not use the place.
Hexagon screw head outside the spiral is round, the middle is concave hexagonal, and hexagonal screws are common to see more of the screw head into the hexagonal side of the kind. Hexagon screwdriver looks like '7', with six hexagonal steel strip cutting in the bend into 90 degrees into a hexagon screw wrench, and hardware tools shop to sell.
Hexagon screwdriver is not the so-called "mobile phone-specific screwdriver", mobile phone-specific screwdriver can be sold on the electronics market selling tools to buy stalls.
Hexagon screw is commonly used in machinery, mainly for fastening, disassembly, not easy to slip angle and other advantages. Hexagon wrenches are generally a 90 ° bend, the end of the bend is short, with a short side of the screw, the long side of the hand can save a lot of power and can better tighten the screws. Long end of a round head (hexagonal cylinder similar to the ball) and flat head, round head can be very convenient to the demolition of the demolition, the installation of some inconvenient wrench parts. The manufacturing cost of the outer hexagon is much lower than that of the hexagon, and its advantages are the screw (wrench force position) is thinner than the hexagon, and some places can not be replaced by the hexagon. In addition, the cost is low, the power intensity is small, the precision of the low mechanical use of the hexagon screw is much less than the outer hexagon.
