Custom Slotted Internally & Externally Threaded Studs

We supply five different size configurations of these custom slotted internally & externally threaded studs to our construction customer.  45K plain steel material is used to produce the parts, with plain and light oil finish.  This specific slotted stud incorporates 1/4-20 internal thread and 1/2-13 external thread.  Both sides are slotted and an extended outer chamfer is required on one side to allow easier installation and removal in the application.  While the different variations have other external thread diameters and length they share the same 1/4-20 internal thread requirement.

Custom Internally & Externally Threaded Studs - Medium Carbon Steel Material

Production of these custom internally and externally threaded studs was run at approximately 10,000 pieces, in medium carbon grade 5 equivalent steel material.  The specific hardness requirement was set to 25-35 HRC.  The custom threaded studs had an overall length of .75" +/.02" with a 45-50 degree tapered point on one side.  Slotted drives were incorporated at both sides for optimal flexibility in our customer's application.  1/2-13 thread was rolled on the outside and 1/4-20 thread tapped all the way through.
