 | Top Product: Clever! Indexing plungers with chamfered pins
JW Winco has developed a new type of indexing plunger (GN 824) that can independently latch into edges and grooves. When the chamfered plunger pin encounters a raised latching geometry, it retracts and then springs back out again once it reaches the latching point. Can be ordered with axial thread for fastening and black plastic knob. In a clever design, the plunger pin can be adjusted by 360 degrees to ensure it encounters the mating surface perpendicularly. Well suited for transport frames, mechanisms, or covers that need to be locked in place quickly and securely.
