How to distinguish external and internal hexagon screw hexagon screw

, The inner hexagonal screw head of the screw is in accordance with the screws were divided into shape, the inner hexagon screws, and screw the bearing capacity of the material and the screws are not related.

Hexagon screw the screw head is round the outside, the middle of the hexagon is concave, the outer hexagonal screws that we have more common flat head screw hexagon Collage was the kind of hexagonal screws.

Main differences:
Hexagon screws commonly used in machinery, mainly with ease of fastening, demolition, not easy to slip angle and other advantages. Hexagon wrench is generally a 90 ° bend in the colt shape, bend one end of the long side of the short screws with a short side of the fight, the long side of the hand can save a lot of power and better able to tighten the screw. Long end is divided into round (Hexagon similar sphere) Peace head, round can easily ramp into the demolition, installation wrench under some convenient location. Hex screw manufacturing costs much lower than the hexagon, and its advantages are conch (wrench force position) than Hexagon thin in some places can not be replaced within the hexagon. Another low-cost, power of low-intensity, low mechanical precision hex screws used much less than the hex.
