Production of these custom double thread lag screws for our construction customer was run in batches of 50,000 pieces using medium carbon steel material with zinc + clear finish.  Overall length measured 10.75" +/- 0.20" and 1/2-6 lag screw thread was incorporated at one side, with the other side using rolled 1/2-13 thread.  Approximately 5.5" of lag thread was designed into the part and 1.2" of the machine screw thread.  The crimped shoulder was set to a height of .37" +/-.02" and a length of .625" to allow use of a wrench during the application.
