Thumb Screws

A thumbscrew resembles a threaded bolt that has a thin, flat head that enables it to be turned with the thumb and index finger. Thumbscrews are available as either plain or shouldered options.

Plain (shoulderless) thumbscrews have a larger head than the shouldered version.

Both types are available with a metric coarse head with a zinc plated finish.

We also currently have a small number of thumbscrews with a BS Whitworth imperial thread, in a self-coloured steel finish.
