J.I.S. or Japanese Industry Standard screws are to be found on Japanese bikes and cars, we are happy to let you know we have increased our range and will continue to add more hard to find fasteners to our growing collection.

All our JIS fasteners are sourced from and made in Japan.

The difference between JIS and ISO is in the size of the head of the screws, JIS are smaller. The A/F spanner size on the nuts and the thread pitch on the M10 and above is also smaller.
