JIS Die Springs


Metric springs conform to the Japanese Industrial Standards (JIS)

For years, we have manufactured high quality springs in all standard ISO sizes and a series of round wire springs, following ISO 9002 quality standards – all in inch sizes. With the springs in this catalog, we are making available a line of true-metric springs, in all the standard JIS sizes and colors.

This extension of the spring line gives more options to customers with exacting requirements, and best of all, makes them available from the same reliable source as the inch springs. If you need help finding a specific heavy-duty compression spring, give us a call.
