Size 5/16-18 - Type 18-8 Stainless Phillips Oval Head Machine Screws

Oval head style screws are countersunk but leave a bit of a rounded section just above the surface for a nice finished look. The length of a oval head screw is determined by measuring from where the taper on the head starts to the end of the screw. Type 18-8 stainless steel has a high resistance to rust and corrosion and may be mildly magnetic. Click on each size below for more information.
