Snap hooks significantly reduce their resistance, becoming vulnerable, if they do not work on their major axis

Snap hooks are the key element of the PPE link chain. They can be made of steel or aluminum alloy.
The snap hooks allow independent attachment. Generally, they have an ovoid shape with a snap closure and a security ring, or they are equipped with screw or automatic closure. For a correct use of a snap hook it is necessary to check the different breaking loads indicated on the device itself.
