Description

■ Head Shape: Hanger Bolt
A special screw that integrates two types of screw parts: a wood screw and a standard millimeter screw (also available in wit standards).

■ Thread Shape: Wit
The Wit Standard is the UK standard. Unlike other standards, the thread angle is 55° and the pitch is roughness than the nations most standard pitch (coarse) prescribed by ISO (International Organization for Standardization) standards.

■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".
