Our engineers reply with a tailored quote within 24 hours.
Convert pieces ↔ kilograms from DIN/ISO dimensions — know your batch weight before requesting a quote, because finishing is priced per kg.
Supported range: 8–200 mm
Weights are computed from DIN/ISO nominal dimensions and steel density (7.85 g/cm³); expect roughly ±10% versus a specific maker's parts. For exact numbers, weigh 10–20 real samples and average (a zinc coating adds under 1%).
Got your batch weight? Hardening and zinc plating are priced per kg. Request a quote — reply within 24 h.
Purchasing orders in pieces, but finishing plants work in kilograms — hardening and plating prices are quoted per kg, and furnace/line capacity is planned by batch weight. This tool bridges the two units so the very first quote is accurate.
Weights are derived from DIN 933 / 912 / 934 / 125 nominal geometry plus steel density — not from any single maker's catalog — so they apply to any brand within roughly ±10%.
Handy rule: the weight of one piece in grams equals the weight of 1,000 pieces in kilograms. An M8 nut ≈ 5 g/pc = 5 kg per 1,000 pcs. When you send work, quote both the piece count and approximate total weight — we cross-check before starting.
Weight per piece in grams — the same number is kg per 1,000 pieces.

About 11 kg (an M10 DIN 934 nut weighs roughly 11 g). An M10×40 hex bolt runs about 33 kg per 1,000 pcs. Use the calculator above for any spec from M3 to M24.
Because hardening and zinc plating are priced per kilogram, and furnace/plating-line capacity is planned by weight per cycle. An accurate weight up front gets you a faster, more precise quote.
Within roughly ±10% of real parts, since head and thread dimensions vary slightly between makers. For critical jobs, weigh 10–20 real samples and average the per-piece weight.
Stainless steel is only 1–2% heavier than carbon steel, so use the chart as-is. Brass is about 8% heavier and aluminium about 65% lighter — scale by density.
