ISO 4014 hex bolt is listed in this library in 7 nominal sizes, from M6 to M24 (M6, M8, M10, M12, M16, M20 and M24). Material grades listed on the size chart are 4.8, 8.8, 10.9, 12.9, A2-70 and A4-80. The underlying data set holds 153 size / grade / finish combinations for this standard, each with its own dimensional table and tolerance notes.
Open the ISO 4014 size chart to select a size and grade and see the full dimensional table. If the part you need falls outside the listed range, send the drawing for a custom quote.
The cluster map above lists DIN 931 (equivalent) and ISO 4017 (equivalent). Treat the table as a starting point: an equivalence entry describes how the standards' dimension tables compare, not a blanket form-fit-function guarantee for a particular part.
Values in the size chart are generated from the same data set as the rest of this library. Where a standard leaves a dimension undefined, the cell shows a dash rather than an estimated value.
