Hey Mike, the minimum length of engagement for 8-32 helicoils are .09
inches (3 turns) before the locking helicoil starts to engage. In
addition, the helicoil is recessed .06 below the surface of the
material. So this will give you 7 more complete turns (with locking)
before your bolt should engage. I would recommend a longer bolt for
fun, however we didn't drill the hole depths deep enough for a longer
bolt. Also, the minimum length of engagement required for a steel
helicoil in aluminum is 0.251 for an 8-32 sized bolt which we have
designed to.
