Amongst Small Tool manufacturers the name of Thomas Chatwin, Limited, stands pre-eminent throughout the British Empire for accuracy and efficiency.
The importance of accuracy to very fine limits of threaded work was not thoroughly appreciated until the Great War brought into prominence the question of interchangeability of component parts manufactured by many different firms and brought to central depots for assembly.
The firm of Thomas Chatwin, Limited, founded in 1849, had, prior to 1914, sixty-five years practical experience of high class screw tool production, and it was therefore only natural that when war broke out they were given work of such importance as the production of Master Check Gauges to Air Ministry, and other munition requirements.
The experience then gained, together with the vast number of screw thread propositions that had been encountered during the years the firm has been in existence, enables Thomas Chatwin, Limited, to undertake with every confidence the manufacture of high class screwing tools for the production of threaded work, both external and internal, to the very fine limits that are demanded by modern engineering practice.
Where accuracy is required for thread proportions, Thomas Chatwin, Limited, should always be consulted.
