WebDec 23, 2002 · Tapping into soft metals such as aluminum is a poor design practice: A. Since most screws are steel, you end up with dissimilar metals (steel on aluminum) which will cause corrosion, pitting, galling, etc. at the threaded interface. B. Aluminums are usually softer than the steel screws and are apt to strip. WebFeb 27, 2024 · Galling happens during installation to fasteners made of alloys such as stainless steel, aluminium and titanium. While the fastener is being tightened, pressure builds between the thread surfaces and breaks down the protective oxide coatings. Without the oxide coating, the thread’s metal high points are exposed to each other. nist body of evidence https://ucayalilogistica.com
