Hook clamps are designed to manually swing into clamping position, then clamp straight down by screw action. These clamps allow clear loading while swung away in an unclamped position. Ideal in tight spaces where high clamping force is required.
Available in three sizes, with 5/16-18, 1/2-13, and 5/8-11 mounting screws (M8, M12, and M16 in metric).
