Both zinc plating and galvanizing is an application of zinc plating. The big difference is thickness: zinc plating is normally 0.2 mils thick. Hot dip galvanizing might be 1.0 mil thick – you get over 5 times the protection with galvanizing. All true galvanizing is...
While some tamper proof screws have unique designs and are virtually impossible to remove without special tools, many designs are better termed tamper-resistant. The most common types of tamper-resistant screws are: one-way screws, spanner screws and a...
Stainless steel, sometimes known as corrosion-resistant steel, can definitely rust. However, it will not rust as readily as ordinary carbon steel, which rusts when exposed to air and moisture. Stainless steel is an alloy that contains, among other things, chromium and...
