Stainless Steel Flanged Hex Head Drilling Screws
 |  |
These corrosion-resistant screws save time and effort by drilling and fastening in one step. The hex head gives you a firm, high-torque grip with a nutdriver or socket. Screws have a flange under the head that spreads the load to prevent crushing thin metal.
Length is measured from under the flange. Head height includes the flange.
410 Molybdenum Stainless Steel—With added molybdenum, these screws resist rusting and pitting better than other 410 stainless steel screws.
