The big difference is whether deformation occurs when the buckling force and tensile force are applied. The buckle standard is between 1.5 and 3.0. Less than 1.2 is non-standard and may cause safety problems.

Conventional standards can refer to the following list:

Buckle for car box: the material needs to be forged at high temperature, and the thickness is between 3mm-5mm.

Vibration equipment type buckle: It is required to be elastic and adjustable, with a thickness between 3mm-2mm.

Outdoor wet type buckle: 304 stainless steel is required to be corrosion resistant. The thickness is between 1.5mm-2.5mm.
