BulletPoint2 : [Material of main body: Carbon Steel]; [Surface treatment of main body: Black Oxide]; [Material of spring pin: Carbon Steel]; [Surface treatment of spring pin: Black Oxide]; [Material of the handle: Nylon 6 (Mat Black)]; [Material of built-in spring: Stainless Steel ] BulletPoint3 : How to use: This Indexing plungers can be divided into two types of mechanical structures with a lock type and without a lock type. This product model PTK is an indexing plunger without a lock type, which can be controlled by pulling the handle the extension and retraction of the spring pin, but the rotation of the handle has no effect on the pin. In use, the handle is pulled out and the pin retracts into the interior of the plunger; release the handle and the pin pops out. BulletPoint4 : This product is an indexing plunger with a built-in spring. The extension and retraction of the pin can be controlled by adjusting the handle, so as to achieve the effect of indexing, positioning or stop limit. Indexing elements are designed to reproduce locked positions defined by indexing bores. Indexing plungers are made up of a threaded body with or without a knob and a plunger, in different high-quality materials: steel, stainless steel and aluminum alloy. BulletPoint5 : Warm reminder: the data on this page are in metric millimetres. As the sizes are measured manually, there may be a slight error, but the error will be less than ±0.5 mm, please understand.
