1/2-13 x 7/8 Flat Point Alloy Steel Socket Set Screw supports equipment builds that call for a full-bearing flat face at the end of the screw.
For 1/2-13 x 7/8, review the flat point around equipment rebuilds where the original point style must be retained and hubs, brackets, and retained components with prepared flats. The broad end face suits prepared flats, repeated adjustment, and jobs where unnecessary deformation of the mating component would create service problems.
The 1/2-13 designation supplies the ordering thread form, and the 7/8 in. length should be checked against tapped depth and bearing location. Match the thread and length to the print because the flat end must land on the prepared contact area. Use the alloy steel callout with the drawing or bill of material, then review the mating surface and operating environment separately.
The UNC series and 13 threads per inch are derived from the thread designation. When the contact seat is flat and aligned, the end face can apply pressure without concentrating the load at one small point. Cold Headers helps keep flat-ended set screw details attached to the size being quoted.
