STALKIN4ELK Jim ,your have a point about compression although I am not sure what the action or reaction is that bends the threaded section of the adapter. Could be some of both compression and stretch. I have not been able to pin point exactly what happens right before bending. For lack of solutions I am just trying to strengthen the "weak link".
There are not tables readably available for compression as there is tensile strength.
The following quote is the reasoning for quoting "Tensile Strength" when comparing metals.
"For most structural materials , the difficulty in finding compressive strength can be overcome by substituting the tensile strength value for compressive strength. This substitution is a safe assumption since the nominal compression strength is always greater than the nominal tensile strength"

In other words if Titanium has a higher tensile strength than low carbon steel or any material that you are comparing it to it is also stronger in compression
Thanks for bringing up the question the more input we get the better ..........We all share this problem no matter what broad head we shoot no broadhead or hunter is exempt
