Index Plungers

Our selection of Index Plungers are produced using a range of high quality materials including Zinc Alloy & Stainless Steel, along with many other carefully chosen elements to increase resistances and longevity. Designed for long term usage within industrial and machine based mechanisms these work by a spring loaded ball or pin being released through a pre-defined hole, either automatically or by pulling a handle/knob. From standard many of the Index Plungers that we offer come with something called a 'locking rest position' which is where the handle can be turned in a certain way to hold the object in place, without the need for a consistent pressure to be applied. Each of the Index Plungers offered below is available in an assortment of sizes and finishes, to meet particular project or product requirements that you may have. 

We stock these Spring Loaded Plungers in a variety of different styles, sizes and finishes as displayed below, including many heavy duty and unique options for more complex uses.

Variations Of Index Plungers

Cam Index Plungers
Cam Plungers are a popular form of Threaded Indexing Plungers, offering an easy to use and adjust handle which interacts with the spring loaded mechanism inside. Used to affix or hold something in position by control, these are often found within objects such as lockers, cabinets and other uses where a door/drawer is held shut.
Fixing Plate Index Plungers
These Fixing Plate versions of Indexing Plunger offer the ability to fix a plate onto your required application, often this could be to operate a basic function such as acting as a catch. Fixed via screw or bolt, these are a truly versatile option thanks to the plate installed.
Lock Position Index Plungers
Lock Position Plungers are useful for all kinds of indexing purposes, with the ability to hold itself in position without the need for constant interaction, either from a human or machine. As threaded index plungers these are compatible with all types of metric threaded components, screwing straight into threaded nuts or inserts as and when required. Such compatibility allows for a quick and stress free installation, along with the ability for fast removal when used temporarily.
Metal Body Index Plungers
Metal Body Plungers feature the same spring loaded plungermechanism and locking rest position as many of their other counterparts, however being made from high quality Steel / Stainless Steel allows their use inside many industries where such materials are a requirement. Indexing Plungers may feature in industries such as food preparation as they could be used to operate basic machine function, such as to hold a control arm in a particular position whilst preparing.

Coming with a locking rest position from standard, these are able to hold an application in place, without the need for any other interaction. Offered with metric threads between M8 & M10 we recommend screwing these into pre-defined threaded holes, which are common-place with modern machinery for the attachment of such products.
