1/2-20 x 3 Oval Point Alloy Steel Socket Set Screw is used where a set screw must contact a curved or irregular seat more naturally than a flat end would.
Because the end is smooth and crowned, this style is often reviewed for adjustment screws, stops, knobs, and retained parts that move during setup.
Alloy steel construction is appropriate where the product specification calls for this family and the oval point geometry matches the intended contact condition.
Typical review areas for 1/2-20 x 3 include curved seats, angled contact areas, and grooved mating surfaces and machine controls, brackets, and bearing-contact locations where smoother point contact is part of the assembly.
The 1/2-20 callout corresponds to UNF thread form and 20 TPI; verify the 3 in. length against tapped depth and the desired bearing location. Confirm that the application needs bearing contact rather than a biting point before approving a substitute. Cold Headers has supplied specialty socket fasteners since 1962, including set screws for uncommon adjustment needs.
