This item is used on multiple models.
These studs will NOT fit on frames where the stud is intended to screw up into the bottom of the frame.
These studs will NOT fit in graphite half frames as the heads are too large to seat down properly in the holes of the half frame.
Used with this type of thin metal clamp. (not included)
Set of Three Pieces
1 Wing Nut 152-200
1 Hex Nut 149-200
1 Rod Clamp Screw 34-200
If you are trying to make a complete clamp set, you need two of these sets combined with the clamp itself.
