A C-clamp with an expeditious adjustment feature. The C-clamp comprises a C-frame having a seat pad and a hole at its either ends. A cylinder is to be received within the hole; the cylinder in turn carrying a clamp rod, which is used for pressing a work piece against the seat pad. The cylinder and the hole permit the clamp rod both to be rotated and to be freely pushed through the cylinder against the seat pad.
