Q: 5. Will this screw fit the small hole on the base of the BENRO PC-0 clamp? There are two SMALL holes on the base and I need such a screw for one of those holes

A: Unfortunately we cannot test these items. The Benro PC-0 is discontinued and the screw is a special-order item. It would be our best guess that the sockets underneath the pan head would be the same and it would be compatible with this screw, but you should contact the original manufacturer to get the exact measurements and specifications.

Q: 7. Can this screw be used for the Benro ball heads. And, for all the OBEN ball and tripod heads? How about MEFOTO?. This seems to be a great product.

A: Yes, It's a standard size and will fit the QR attachment plates. Those plates should fit almost all ball heads except for Manfrotto and RRS (Really Right Stuff) which has their own size of plates which might require something else although it might fit them also. However, the 1/4 -20 is standard for a ton of things.

Q: 8. I wish to purchase a Sirui G-10X Ball Head and replace the screw with this one. Do I use this one or the QR version?

A: The ring is about 1/2".
