Spring plungers are hollow grub
screws with a captive spring loaded hardened ball protruding from one end.
They are commonly used in machine
tool indexing applications where a pre-defined positional stop is
required.
We stock these black phosphated
finish high tensile steel spring plungers with slot drive, from M3 to M10.
Other larger sizes are also available
on request.
