• By providing intermediate male screws, long stroke is realized.
• An epoch-making screw support that solves the problem of shifting the position and scratching the workpiece when the male screw is turned under load by turning the intermediate male screw.
• The adjustment of the middle male screw can be fine adjusted because the upper and lower screws have different pitches in the same direction and can be operated with light force.
• Locking screw (with lock piece) to lock the external screw prevents loosening of the screw.
• Use screw support tips for uneven surfaces and irregular workpieces.
• Ideal for supporting heavy objects, adjusting the height of clamps, and suppressing chatter during cutting.
