Most screws are machinable steel with hardened flight surfaces, either via a welded-on cap around 0.040 to 0.080 in. (1 to 2 mm) thick or by nitriding the whole surface. The latter method is cheaper, but prevents alteration of the flight depth later; the useful life depends on the depth of nitride penetration.
