Thumb Screws - Plain
A thumbscrew resembles a threaded bolt that has a thin, flat head that enables it to be turned with the thumb and index finger.
The head of a shoulderless thumbscrew is larger than that off the shouldered version.
Shoulderless thumbscrews 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.
