3. Applications:
The stainless steel machine screw has plain finish/polished and a
flat head with a slotted drive, and meets American Society of
Mechanical Engineers ASME B18.6.3 and Society of Automotive
Engineers SAE J82 specifications. Steel is often used in
applications where strength is the primary consideration. The
stainless steel have better corrosion resistance than the carbon
steel. The slotted drive has a linear slot for use with a
flat-blade driver. The flat head is cone shaped for use in
countersunk holes and has a flat top that fits flush with the mated
surface.
Machine screws are threaded fasteners that are typically used with
nuts or drilled and tapped (threaded) holes. Machine screws are
available with a variety of head shapes, which determine how the
screw interacts with the mating surface, and drive styles, which
determine the type of driver required to install and remove the
screw.
