Types And Causes Of Nut Surface Defects-Caplillary Crack

In previous articles, we described bursts in fastener surface defects, including their classification and the causes of their formation. In this article, as a professional fastener manufacturer, we will continue to introduce capillary cracks in the fastener surface.

A crack is a longitudinal surface defect formed by the cracking of narrow wrinkles on a material.

Causes of cracks: Cracks are usually inherent defects in the raw materials used to manufacture fasteners.

Note: All thread sizes with cracks shall not exceed 0.05D(D-thread nominal diameter).
