SPECIFICATIONS
A Hex nut with an enlarged circular base flaring out from the bottom of the nut, and a metric thread pitch. The bearing surface of the flange is smooth. Class A4-70 nuts are intended for use with screws and bolts of similar material where greater resistance to extreme temperatures and greater resistance to corrosion is desired. The flange design will span oversized or poorly aligned holes. The flange provides a more uniform bearing stress to clamp-force ratio.
