Benefits #
The 5/16-inch stainless steel countersunk machine screw addresses flush-mounting in imperial-dimensioned assemblies where metric fasteners are not interchangeable. A2-70 grade provides 700 MPa tensile strength with inherent corrosion protection. The 82° head angle matches ASME B18.6.3 standard countersink tooling. Phillips drive compatibility ensures installation with standard hand and powered drivers.
