Acorn Nuts Metric A2 Stainless Steel
An acorn nut is a nut that has a domed end on one side. When used together with a threaded fastener with an external male thread, the domed end encloses the external thread, either to protect the thread or to protect nearby objects from contact with the thread. In addition, the dome gives a more finished appearance. A2 Stainless Steel (SAE 304 stainless steel) is the ISO designation for a stainless steel comparable to 18-8 and has excellent corrosion resistance.
