I have just seen an internet clip on which Kowa are boasting about the new 88 foot (dual bolts ).
I find it more than a little hilarious it has taken over 125 years for them to even try and help to stop their scopes rotating on tripod plated to the frustration of all the customers most of whom are still struggling with this problem.

Two screws are the belt and braces solution but provided a quick release plate has an anti-rotation pin and a metallic top surface (zero compliance), no problems should occur.
Even moderate torque will generate a high compressive force, and friction between the two surfaces, more than enough to cope with any shear or torsional loads. After all, a scope only weighs about 2,5 kg at the most.

Well I have seen birders scopes work loose on the trip out in the boot before the birdings even begun and there are that many tripod plates with rubberised surfaces that not many seem to get the chance of metal to metal and I am always afraid of overtightening and stripping the thread so you may know something we dont there does seem to be quite a few questions about anti rotation pins and scopes coming loose over the years manfrotto brought out a special plate ( at a ridiculous price) some at the "rotation problem".
