For additional loosening resistance, use a lock washer on the nut side as well as on the head side. Split lock washers may not be as effective on extremely hard metals as the edges at the split cannot dig in to the surface as well.

None were overcoated so that bolts were difficult to install a definite plus! An excellent price for bulk washers. Boxes are quite flimsy but so are the ones bought at box stores, just plan on re containering them

These worked just fine with the galvanized screws ordered to keep my picnic table together!
