RS PRO Index Plunger

This RS PRO index bolt has a fitted spring to push the bolt attached to one item into the corresponding opening of a different item. This makes the bolt useful for precision-positioning parts in machinery, as it ensures that the parts are aligned perfectly. An index bolt like this one is commonly used in factories and workshops for machine assembly.


The zinc plating of this steel bolt provides corrosion resistance for long-lasting performance in harsh environments. It's easy to install as its thread lets you screw it securely into place.


This bolt conforms to US (ANSI/ESD S20.20:2014) and European (BS EN 61340-5-1:2007) electrostatic control standards, so it won't damage equipment via electrostatic discharge. It also complies with the Restriction of Hazardous Substances (RoHS) directive, meaning it contains only trace amounts of any harmful materials. It also comes with a three-year warranty for additional peace of mind.
