connector 605 functions as a turnbuckle after the connection of the first end 305 and the second end 310 to the plunger and the pony rod respectively the clamp connector 605 may be coupled to the first end 305 by rotating the clamp connector 605 relative to the first end 305 simultaneously the clamp connector 605 may be coupled to the second end 310 by rotating the clamp connector 605 relative to the second end 310 the blind holes 325 of the clamp connector 605 and or the first end 305 may be used to tighten the clamp connector 605 to the first end 305 and the second end 310 a torque value may be specified for the threaded connection 330 to ensure the threaded connection 330 does not loosen over time embodiments of the plunger clamps 300 500 and 600 as described herein easily secures a pony rod to a plunger of a fluid end with a connection that is enables proper torqueing of fasteners which enables safer operation the plunger clamps 300 500 and 600 may be disassembled such that each side the first end and the second end can be installed without being connected to each other which facilitates tightening of fasteners to the required torque values the plunger clamps 300 500 and 600 as described herein is usable on existing equipment without any additional machining or retrofitting to existing fluid ends plungers and or power ends the plunger clamps 300 500 and 600 may be installed without removal of the plunger from the fluid end which saves considerable time the plunger clamps 300 500 and 600 may be installed using standard tools such as spanner wrenches or packing nut bars the plunger clamps 300 500 and 600 are significantly cheaper to manufacture than conventional.
