Thread galling causes
WebIn bolting, thread galling appears during fastener tightening as pressure builds up between the contacting and sliding thread surfaces. In extreme cases galling leads to seizing, which is the actual freezing together of the threads and bolt lock-up. Continued tightening may cause the fastener to be twisted off or result in ripped out threads ... Galling is often found between metallic surfaces where direct contact and relative motion have occurred. Sheet metal forming, thread manufacturing, and other industrial operations may include moving parts, or contact surfaces made of stainless steel, aluminium, titanium, and other metals whose natural development of an external oxide layer through passivation increases their corrosion resistance but renders them particularly susceptible to galling.
