Product Overview

Spring Plungers Steel Screw

The spring plunger is also known as the positioning column, ball screw, spring screw, etc. It is a product involving vertical stroke, in which the front pin is pressed till the pin sinks into the body and then the front pin can be ejected through the built-in spring. It can be used in mold release, workpiece lifting and positioning, etc., which can be widely applied in medium and low-precision mechanical devices, fixtures, molds, automation machines, etc.
