GRADE 2 HHCS, HDG (INCH)
Hex Cap Screws are very common in OEM markets as well as construction and other industries. The most common is made out of low carbon steel in a Grade 2, 5 and 8 for US measurements. These particular screw with "Hot Dipped Galvanized" Finish primarily are used out doors to prevent rust and decay. The threads require a special Female thread, so if purchasing these, make sure you also ask for the Galvnized to go along with them as well.
