Bolt stud made of Stainless Steel for the Thumbhole Stock 78.
The Thumb Hole has the longest stud. The bolt studs have a larger thread one end and a smaller thread the other to fit into the gun. If you want the nut as well in Stainless Steel then select it in the options tab. I have added the SS Stud and Blind and through thumb Nut as well. As you can see I have designed the thumb nut without the ugly hole that went right through so I think it looks neater.  On rare occasion you may have to put a washer or so on the stud to make it tight.

Photo shows the blind nut. The through one obviously has a hole straight through but is not show yet.
