Bolt Dimensions

Look up standard bolt thread dimensions and stress areas. The library covers:

• Metric threads (ISO 724 / ISO 898-1)
• Unified inch threads (ASME B1.1)
• GOST threads (GOST 24705 / GOST 9150)

Three ways to find a bolt:

• Designation — search by name, e.g. M12 or 1/2-13.
• Thread standard — pick ISO, ASME or GOST.
• Threshold filter — set a minimum stress area or diameter.

Click any result to see the full thread geometry — pitch, pitch diameter, minor diameter, stress area, and hole diameter. Inch threads also keep their original inch values.
