Carbon Steel Stud:

  • Have an after swage diameter equal to the nominal thread size.  Because they have a greater wall thickness in the swaging area, they can sometimes have an increased holding strength on strand construction such as 1x19.  These threaded studs are well suited for some of the toughest applications.
