■ Head Shape: Eye bolt
The head is a ring shape. The ring part is used to lift objects through wire, rope, or to hang chains.
The length of the eyebolt is determined by the thickness of the thread (nominal diameter).
There is no special tools for tightening the eyebolt, so you can tighten it by hand, and finally insert a rod or other similar to the ring to tighten it.

■ Thread Shape: Fine
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.

■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".
