Dear Welder Series… minimum thread depth?

Dear Welder Series…
On the 5/8 – 18 adjuster kit, assuming it has approximately 2.5″ of threads on it, what is the least amount of thread that can be screwed into the 4-link bar and still be considered safe? The application is a 1952 Chevy pickup utilizing an 8.8″ Ford Explorer rear axle. It will have a 400hp small block for power. Thanks.

Dear Joe…
Joe, the generally accepted standard for minimum thread engagement is the diameter of the fastener, or in this case, 5/8”.

Thanks for asking.
