[M10×35 (P=1.25)]

■ Head Shape: Hexagonal App Set with Flange & Serate
The hexagonal head has a round dump on the top of the head with a conical brim, called a flange. The seated serate on the brim side prevents the seat from falling into the other material and provides a slight loosening effect.
Tighten using a tool such as a spanner, wrench, etc.

■ Thread Shape: Fine [Full screw]
Finer than the nations most standard pitch (coarse) prescribed by ISO (International Organization for Standardization) standard. Compared to coarse threads, it has a shallow valley and a larger cross-section area which makes it less likely to loose. Please note that there are multiple sizes of pitch depending on the thickness of the screw. Primarily used where precision is required.
In addition, the "full screw" is the shape of all the threads from the tip of the head to the head seat.

■Material: Iron
"Iron" is "steel" and is an alloy of iron containing carbon.
Although it is commonly used in many circulations, it is cheap materials, but due to the downside of it is easy to rust, many surface treatments will reduce corrosion.

■Surface treatment: Trivalent white
It has the same corrosion resistance as "chromate" and has the same possibility of imitation self-healing.
Unlike hexavalent chrome, it is non-toxic and compliant with RoHS directive. So it is used as an alternative to unichromate/chromate.
Color is "Silver Color".
