M12 x 130 DIN 444 Steel swing bolt

What are eyebolts?

An eye-bolt is a fastener with a loop or eye at one end and a threaded shaft on the other. It is used to attach ropes, and cables, or secure a bolt through, allowing for lifting or hanging items.

What standard are these eyebolts made to?

WDS swing/eyebolts are manufactured with reference to DIN 444 Type B standards, which specify the dimensions of these components. This standard ensures that the eyebolts meet quality and performance criteria, providing reliability and safety in various applications. The "Type B" designation indicates a specific variation within the DIN 444 standard, typically referring to the size and shape of the eye and shank as well as tolerances. These are made with this DIN specification in mind and some dimensions may differ.

What are some design features?

WDS eyebolts are manufactured from 220M07 steel, a low-carbon steel known for its toughness and machinability, which enhances the durability of the eyebolts. The threads on these eyebolts are rolled rather than cut, which improves their strength and fatigue resistance by compressing the steel and creating a stronger thread. Additionally, the central hole of these eyebolts is toleranced at H9, ensuring a precise fit with minimal play, which is crucial for maintaining stability and alignment if required.
