Bolt weight chart.
Approximate carbon-steel mass for DIN 933 / ISO 4017-style full-thread hex screws, shown in kilograms per 1,000 pieces. For partial-thread bolts, large diameters, inch sizes and complete sets, use the calculator.
DIN 933 full-thread reference
kg / 1,000 pieces. Plain carbon steel; published catalogue weights are approximate and actual finished mass varies with dimensional tolerance and coating.

Full thread vs partial thread
DIN 931 / ISO 4014 partial-thread bolts retain a plain shank, so the mass is not identical to DIN 933 at the same diameter and length. The United Exim calculator treats the geometry separately rather than applying this table blindly.
