Launching Engineering Reference: free lookup tables based on JIS and ISO

Engineering Reference is now live on the MINATA website, under the Knowledge tab, free to use in Vietnamese, English and Japanese.

The first set covers tables used every day in design and machining: tap drill sizes for metric threads, hole and shaft fits, surface roughness Ra, hardness conversion, geometric tolerance symbols, bolt tightening torque, keys and keyways, common materials, and Japanese–Vietnamese technical terms. Each table names its source standard and has a filter for quick lookup.

The tables are for reference. Before applying them to a real product, check the current standard and the manufacturer's catalogue.
