Height limitations dictate a short blind hole with limited thread depth and the thread is usually brass or stainless steel.Scope feet are usually aluminium and good engineering practice would dictate the use of more than 4 thread turns on the mounting screw so that sufficient torque could be applied that any shear loads are carried by the friction between QR plate and scope foot.If the scope has a 3/8" mounting thread then one should use a QR plate with a 3/8" screw and not be tempted to use the 1/4" to 3/8" adapter.John</blockquote>
