We provide our customer a small batch of these custom stainless steel double end studs at just over 100 pieces.  They wanted to replicate existing parts but did not have any drawings or prints.  We used a sample piece provided to replicate all dimensions to a +/-.01" tolerance.  1/4-20 thread is incorporated on the larger diameter side and 10-32 on the other, with approximately half the thread turned down into a dog point.
