Flat Head Inch Socket Screws
Flat Head Socket Screws are the fastener of choice in high precision, high strength assemblies requiring a finely tooled appearance. The V-shaped 82° head allows the screw to be countersunk into the mating surface material, affording a completely flush profile. Because of their alloy composition and heat treating that they undergo resulting in extremely high tensile and yield strength, a given size of a Flat Head Socket Screw may be comparable in strength to the next larger diameter of a common, low-carbon steel flat head machine screw. This has the unique advantage of potentially fewer screws needed in a particular design to achieve specific clamp loads. Fewer screws = lighter assemblies and reduced cost. It is easy to understand the appeal of this versatile, ubiquitous fastener.
