Hex Socket Flat Head Cap Screws（Detailed Shape：Flat Head）

This is a category page for hexagon socket head cap screws. For MISUMI, you can select from M2 to 20, length of 3 to 150 mm, 4 types of material and 13 types of surface processing.
In addition to the JIS standard, we handle former JIS, SSS, ISO standards, etc.

[What is a countersunk bolt?]
It has a countersunk head, which allows the fastening surface to be made flush by opening a counter bore on the mating material and fastening. Therefore, it is often used in places such as hinges where you do not want bolt heads to protrude.
It is similar in shape to a small crosshead countersunk screw, but since a hex wrench is used for the countersunk bolt, it can be used in a place where it needs to be tightened more securely.
