Custom Binding Post - Female In 316 Stainless Steel Material With 6Lobe (Torx Alternative) Drive

These custom binding posts were manufactured using 316 stainless steel material, with 3/8 coarse internal thread tapped as close to the head as possible and a T30 drive cold headed all the way through.  The head diameter is 1.13" head height at .19" +/- .01".  The shoulder outside diameter is set to .63" and measures .75" in length, with both dimensions also limited to a +/-.01" tolerance.  4340 alloy steel material was also considered as an alternative, offering greater strength when heat treated than the 316 stainless steel material version pictured here.
